Answer:
Step-by-step explanation:
The sum of interior angles is equal to exterior angle
Given the following
Interior angles = 5x + 10 and 58
Exterior angle 11x+2
According to the postulate:
5x + 10 + 58 = 11x + 2
5x + 68 = 11x + 2
Collect like terms
5x -11x = 2 - 68
-6x = -66
x = -66/-6
<em>x = 11</em>
<em>The value of x is 11</em>
<em></em>
22°
sin(theta)=7/19
m(theta)= arcsin(7/19)=22°
its B
