Answer:
512
Step-by-step explanation:
each number is a sum of the two numbers in the row above it.
Answer:
m<a = 77
m<b= 103
Step-by-step explanation:
m<a+m<b = 180(supplementary angles)
3x/8+50+x+31=180
3x/8+x+81=180
(3x+8x)/8=180-81
3x+8x=99*8
11x=792
x=792/11
x=72
now
m<a=3x/8+50
=(3*72)/8+50
=77
m<b=x+31
=72+31
=103
180-65=115°
that's the answer
