Question

Someone please help me

The options are :
A) 45
B) 135
C) 120
D) 75

Answer 1

45

Explanation:

cuz 3 times 45 = 135 double that and that will be 270

then add 45+45= 90

last add 270 + 90 = 360 which is all of the measures inside a quadrilateral

Answer 2

x + 3x +x + 3x = 360
8x = 360
x = 45

answer
A) 45
