Answer:
x = 12 , -2
Explanation:
For the first Question ,
we Know that by VOA , The angles are equal to 40*
and by being a linear pair , we get 180 - 110 = 70*
By exterior angle property , 40 + 70 = 9x - 2
= 110 = 9x - 2
9x = 108
x = 108/9 = 12
For the second question ,
By VOA , we know that the interior angles of the triangle are x+74 , 37 + x and 73
By Angle - sum Property , x+ 74 + 37 + x + 73 = 180
2x + 184 = 180
2x = 180 - 184
2x = -4 , so x = -2
