Question

Measurements I suck at it​

Answer 1

a is 65

b is 73

c is 17

d is 138

Answer 2

a = 65

b = 73

c = 17

d = 138

Explanation:

d + 42 = 180

d = 138

c + d + 90 + 115 = 360

c + 138 + 205 = 360

c + 343 = 360

c = 17

90 + b + c = 180

90 + b + 17 = 180

b + 107 = 180

b = 73

a + b + 42 = 180

a + 73 + 42 = 180

a + 115 = 180

a = 65
