(4x-8)"
131*
61"

Answer 1

x = 19.5

Explanation:

The interior angles of a triangle will ALWAYS have a sum of 180°

Answer 2

Answer: 19.5

Explanation:

obtuse + acute = 180

131 + t = 180

t = 49 degrees for the top angle

49 + 61 + 4x-8 = 180 degrees in a triangle

110 + 4x - 8 = 180

102 + 4x = 180

4x = 78

x = 19.5
