Question

Please help answer please

Answer 1

x = 91.

Putting 91 into the two equations inside the triangle makes the angles 59 and 49, and makes the outside angle 108. Those two angles must add and equal the outside angle, and they do, meaning x = 91.

Answer 2

x = 19

Explanation:

x-42+x-32+180-x+17 = 180

3x +123 = 180

3x = 57

x=19
