Answer:
The answer is 15x+10b-45y+50 which is the choices C.
Step-by-step explanation:
5(3x+2b-9y+10)
15x+10b-45y+50
Answer:
(2,-9)
Step-by-step explanation:
This is true, for example 1+1=2,3+3=6,21+21=42
Answer:
Option (C)
Step-by-step explanation:
Since angle 'a' is the inscribed angle of the given triangle
Therefore, angle measure of the intercepted arc will be equal to the double of the inscribed angle.
x = 2a ⇒ a =
By the tangent-chord theorem,
"Angle between a chord and tangent measure the half of the angle measure of intercepted minor arc"
= 40°
Therefore, a = = 40°
Option (C) will be the answer.
