Which expression has the same value as sin(20∘)?A)cos(10∘)B)cos(20∘)C)cos(40∘)D)cos(70∘)

Answer

The red line represents y = x + 1

The blue line represents y = 2x - 7

We can see that the two lines and equation intersect at (8, 9)

Solution

x = 8

y = 9

Explanation

The two equations are

y = x + 1

y = 2x - 7

To solve this graphically, we will plot the two equations on the same graph and the solution will exist at the point where the two lines meet.

To plot the lines for each of these equations, we will use intercepts to obtain two points on each line and then connect the two points to get each of the lines.

y = x + 1

when x = 0

y = x + 1

y = 0 + 1

y = 1

First point on the line is (0, 1)

when y = 0

y = x + 1

0 = x + 1

x = -1

Second point on the line is (-1, 0)

The two points are (0, 1) and (-1, 0)

y = 2x - 7

when x = 0

y = 2x - 7

y = 2(0) - 7

y = 0 - 7

y = -7

First point on the line is (0, -7)

when y = 0

y = 2x - 7

0 = 2x - 7

2x = - 7

Divide both sides by 2

(2x/2) = (-7/2)

x = -3.5

Second point on the line is (-3.5, 0)

The two points are (0, -7) and (-3.5, 0)

The graph of this question will now be presented under answer and the point of intersection will bw evident.

A) To find the external angles of the quadrilateral we will walk around the shape measuring every turn we take. We will start on the A point, rotate clock-wise and move in the direction of point "B", when we get there we will rotate clock-wise again and walk to the direction of point "C". When we do get to the point C we will notice that we rotated 180 degrees in relation to the initial position we had in point A. Moving forwars we will now rotate clockwise and go to the poind D, rotate clock-wise again when we get there, performing all the rotations needed. We will notice that we have the same orientation from the beginning, this means that we rotated 360 degrees. In other words the sum of the external angles of the quadrilateral is 360 degrees.

B) Yes, any regular polygon will have the sum of its external angles equal to 360 degrees.

C) The internal and external angles are suplementary. This means that the sum of these angles must be equal to 180 degrees, therefore:

Since each external angle is the same as "180 degrees" minus the internal angle that is close to it we can represent the sum of the external angles as 360 degrees and use the mentioned relation to convert them into internal angles. If we isolate them as a sum we will find the value of the sum of the internal angles.

D) If we look at the fith line from the solution above we will notice that the sum of internal angles is represented by "(4-2)*180", the polygon had "4" sides. This means that for one that is 5 sides we should expect that it would be "(5-2)*180" and so on. So the formula is:

Where "n" is the number of sides of the polygon.

Apply the distance between 2 points formula:

We have the points:

We need to solve the equation:

Then:

Therefore, t=-12.

To find the length of the segment use the Pythagoras theorem below:

From the graph, we have:

AB = 15 - 3 = 12

BC = 7 - 2 = 5

Let's solve for the length of the segment AC:

Take the square-root of both sides:

Therefore, the length of this segment is 13

ANSWER:

13

Since the elongation E varies directly with the weight W, they are related as follows

where k is the constant of proportionality. In order to find k, we can substitute the given values, that is, when E=2, W=15, then we have

Then, k is given as

Therefore, our formula for any E and W is

Now, in order to find E in the second case, by replacing W=10, we get

which yields

Therefore, the answer is

So, Sin QOP = QP/OQ = OPPOSITE/ Hyp

Then, cos PQO = QP/OQ = Adjacent/ Hyp

Using the same logic, Cos ROQ = RO/OQ = Adj/Hyp

Then, sin QPO = RO/OQ = Opp/Hyp

The slope will be 4/5.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The points are,

(0, - 1) and (5, 3)

Now,

Since, The slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is;

m = (y₂ - y₁) / (x₂ - x₁)

So, The slope of the line passing through the points (0, - 1) and (5, 3) is;

m = (y₂ - y₁) / (x₂ - x₁)

m = (3 - (-1)) / (5 - 0)

m = (3 + 1) / 5

m = 4/5

And, The y - intercept is at x  = 0

Thus, The slope will be 4/5.

And, The y - intercept will be (0, - 1)

Answer

x = 85°

Explanation

The image of this question shows that the two angles 20° and (x - 15)° both sum up to give a right angle (90°). So,

20° + (x - 15)° = 90°

20° + x - 15° = 90°

x° + 20° - 15° = 90°

x + 5° = 90°

x = 90° - 5°

x = 85°
