Question

PLEASE HELP!!!!

what is the value of s?

PLEASE LOOK AT PICTURE!!!!!

Answer 1

s = 87

Explanation:

Let´s call the missing internal angle "a"

a + (s + 49) = 180

a + s = 180 - 49

a + s = 131

a = 131 - s

The sum of the internal angles of a triangle = 180°

(s-38) + s + a = 180°

(s-38) + s + (131-s) = 180

s + s - s + 131 - 38 = 180

s + 93 = 180

s = 180 - 93

s = 87
