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.
Answer:
81
Step-by-step explanation:
RZT = 137
RZS = 56
SZT = 137 - 56 = 81
The answer is 180.
12 times 15 equals 180
18 times 10 equals 180
20 times 9 equals 180
The answer is 7 distributed and you get 3x-15=6 add 15 to both sides you get 3x=21 and x equals 7
