Given: t is tangent at B
is diameter
If m = 110°, then m =
70
80
110
Answer:
70
Step-by-step explanation:
Given
∠PDB = 110°
PDis the tangent to the circle whose centre is E
Construction
Join points D and E.
∠DPE= 90° [Since angle in a semi circle is 90°]
Also ∠PDE = 90° [Since radius ⊥ tangent]
From the figure we have,
∠PDB=∠PDE + ∠DBE
i.e. 110° = 90° + ∠DBE
Therefore, ∠DBE =20°
Now in ΔBED, BE = ED [Radii]
So, ∠EDB = ∠EBD =20°
In ΔBPD, we have
∠DPE = 90° & ∠DBE = 20°
Therefore, ∠DPB = 70°
Answer:
70 is the correct answer

REASON
Kyle had a balance of -5 dollars in his checking account. After he deposits a certain amount of money into the account, the balance is now 15 dollars.
How much money did Kyle deposit into his checking account?
Answer:
$20
Step-by-step explanation:
start with an equation. 15-(-5)=x. double negatives make positive so it becomes 15+5=x. therefore 20=x (x being the number kyle deposited).

If the slope is -3 and (1, 2) is a point on the line, what is the equation of the line?
Answer: y=-3x+5
Step-by-step explanation:
First write in point slope form, y-y1=m(x-x1) which is y-2=-3(x-1). Then distribute the -3 and add the negative 2 to the other side to solve for y.
How tall is a building 100 feet away if the angle of elevation from the ground to the
top of the building is 20 degrees?
Answer:
i think it is 50ft but i'm not too sure
Step-by-step explanation:

Step-by-step explanation:
Which of the following equations represents a line that is parallel to the line 3x - 2y = 12
and passes through the point (7, 10)?
Answer:
Step-by-step explanation:
12=3x-2y
2y+12=3x
2y=3x-12
y=(3x-12)/2
y=mx+b
To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be
y=1.5x+b, using point (7,10) we can solve for the y intercept or b
10=1.5(7)+b
10=10.5+b
b=-0.5 so our line is
y=1.5x-0.5
Question 1 options:
68°
136°
158°
112°
9514 1404 393
Answer:
(d) 112°
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary.
∠P = 180° -∠R = 180° -68°
∠P = 112°
Answer:
112 degrees.
Step-by-step explanation:
This is an isosceles trapezium.
So the required angle = 180 - 68 = 112.
3) The cost of a movie ticket and a candy bar is $5. The cost of 2 tickets
and a candy bar is $8.75. How much is a candy bar? *
Answer:
$1.25
Step-by-step explanation:
Given data
let the movie ticket be x and the candy bar be y
x+y= 5-------------1
also
2x+y= 8.75--------2
solve 1 and 2
x+y= 5
2x+y= 8.75
from 1
x= 5-y
put this inplace of x in 2
2(5-y)+y=8.75
10-2y+y= 8.75
10-y= 8.75
10-8.75=y
y= 1.25
Hence candy bar is $1.25
please do, thank you

Are all parallel lines congruent?
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments. If you drag any of the four endpoints, the other segment will change length to remain congruent with the one you are changing.

Given:
In a right angle triangle ABC, [tex]\angle B=90^\circ,x=8.7\ m[/tex], and [tex]\theta = 45^\circ[/tex]
To find:
The value of AC.
Solution:
In a right angle triangle,
[tex]\cos \theta =\dfrac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos \theta =\dfrac{BC}{AC}[/tex]
[tex]\cos (45^\circ) =\dfrac{8.7}{AC}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{8.7}{AC}[/tex]
On cross multiplication, we get
[tex]AC=8.7\times \sqrt{2}[/tex]
[tex]AC=12.30365799[/tex]
[tex]AC\approx 12.304[/tex]
Therefore, the measure of AC is 12.304 m.
