What are m4 and m1.............................................
1 answer:
Answer:
m<1 = 136
m<4 = 44
Step-by-step explanation:
Exterior angle thm:
<2 + <3 = <4
4x + 2 + 5x - 3 = 8x + 4
9x - 1 = 8x + 4
9x - 8x = 4 + 1
x = 5
m<4:
8x + 4
8(5) + 4
40 + 4
44
m<1 and m<4 are supplementary (they add up to 180) so:
m<1 + m<4 = 180
m<1 + 44 = 180
m<1 = 136
