Answer:
The answer is below
Step-by-step explanation:
The question is not complete, a complete question is attached.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled, obtuse, acute, scalene, isosceles, equilateral triangle.
Trigonometric identities are used to show the relationship between the sides and the angles in a right angled triangle. Below are some trigonometric identities:
sin(θ) = opposite / hypotenuse; cos(θ) = adjacent / hypotenuse; tan(θ) = opposite / adjacent
The hypotenuse is the longest side in the triangle.
From the image attached:
sin(α) = opposite side / hypotenuse side
sin(α) = 7 / 25

Step-by-step explanation:
A car travelled at 50 km/hr for 3 hours How far did the car travel?
Answer:
25km
Step-by-step explanation:
50 km = x km
1 hr 3 hrs
From there, you cross-multiply and solve for x.
(50 km)*(3 hrs) = (x km)*(1 hr)
x km = (50)*(3)/(1) = 150km
Now, your other question can be answered the exact same way. 30 minutes is the same as 1/2 of an hour, so just put 0.5hrs in where the 3hrs was in the previous problem. So to show you how it works once more, here are your calculations:
50 km = x km
1 hr 0.5 hrs
(50 km)*(0.5 hrs) = (x km)*(1 hr)
x km = (50)*(0.5)/(1) = 25km

Find the area of the compound figure. Round your answer to 2 decimal places if required. (Use π = 3.14)
Hello! I’ve been stuck on this problem for a while and—though I know the answer—I’m not sure how to get to it? Please help!
Answer:
first you will need to break the shape into a semi circle and a triangle.
then solve the area of the semi circle. which is
[tex] \frac{(3.14) \times r ^{2} }{2} \\ [/tex]
[tex] \frac{(3.14) \times 4.6^{2} }{2} \\ = 33.22[/tex]
Then solve the area of the triangle.
First work out the height of the triangle, which is
[tex]13.4 - 4.6 = 8.8[/tex]
then the area. which is
[tex] \frac{1}{2} 4.6 \times 8.8 \\ = 20.24[/tex]
now calc. the two figures. which is
[tex]20.24 + 33.22 \\ = 53.46[/tex]

Given b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C. What is the area of the triangle? Round to the nearest hundredth.
Answer:
1.73 units
Step-by-step explanation:
The area of a triangle with sides a, b, c and angles A, B, C is given as
Area = 1/2 bc sin A
Given that b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C then the area
= 1/2 * 4 * 1 * sin 120
= 2 sin 120
= 2 * √3/2
= √3
= 1.732
To the nearest hundredth = 1.73

Find the area of the shaded region
Answer:
40
Step-by-step explanation:
area of shaded region = area of whole figure - area of non shaded region
area of whole figure: The whole figure is a rectangle
The area of a rectangle can simply be calculated by multiplying the width by the length
The given width is 10ft and the given length is 8ft
Hence area of whole figure = 10 * 8 = 80ft²
Area of non shaded region: the non shaded region also creates a rectangle
Like stated previously the area of a rectangle can simply be calculated by multiplying the width by the length
The given width is 5ft and the given length is 8ft
Hence, area of non shaded region = 5 * 8 = 40ft²
Finally we can find the area of the shaded region.
We can easily do this my subtracting the area of the nonshaded region from the area of the whole figure
If we have identified that the area of the whole figure is 80 and the area of the non shaded region is 40
Then, area of shaded region = 80 - 40 = 40ft²

i've ask this 3 times and didn't get a correct answer
Answer:
240
Step-by-step explanation:
So to do this problem, you have to find the area of each 2d figure. To start off, you need to find the top sides. (to make this easier I won't show the work)
Green- Top & bottom: 16. Sides (4): 28
Pink- Top & bottom: 8. Sides (4): 20
Now you add it all up.
32+112+16+80=240
Answer:
224 in^2
Step-by-step explanation:
The pink rectangular prism has the dimensions 2 x 4 x 10 and the green has the dimensions 4 x 4 x 7. The formula for the surface area of a rectangular prism is:
2(lw + wh + lh)
We can substitute to find the surface area of both pink and green:
Pink
2(4 x 4 + 4 x 7 + 7 x 4)
2(16 + 28 + 28)
2(72)
144
Green
2(2 x 4 + 4 x 10 + 2 x 10)
2(8 + 40 + 20)
2(68)
136
The sum is 280. We have over-counted the part where the two prisms are next to each other. The area of the counted rectangle is 4 x 7 or 28. We over-counted twice, so we need to subtract 2 x 28 or 56.
280 - 56 = 224 in^2

To do this, we make of sine rule.
[tex]\frac{a}{\sin A} = \frac{b}{\sin B} =\frac{c}{\sin C}[/tex]
In this case:
[tex]x = ??[/tex]
[tex]X = 68[/tex]
[tex]a = 66[/tex]
[tex]A = 35[/tex]
So, we have:
[tex]\frac{x}{\sin 68} = \frac{66}{\sin 35}[/tex]
Make x the subject
[tex]x = \frac{66}{\sin 35} * \sin 68[/tex]
Using a calculator, we have:
[tex]x = \frac{66}{0.5736} * 0.9272[/tex]
[tex]x = 115.063* 0.9272[/tex]
[tex]x = 106.68[/tex]
[tex]x \approx 107[/tex]

You estimate that your new business's revenue will grow at a compounded rate of 30% each month for the first 6 months. If your third month's revenue is estimated at $5,000, what is your second month's revenue? (Round to the nearest dollar.)
a) $2,945
b) $3,846
c) $4,012
d) $4,333
Answer:
b
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
let a = second month's revenue
5000 = a(1.3)
a = 5000 / 1.3 = 3846
