Answer:
x = 10
m<A = 132 degrees
m<B = 48 degrees
Step-by-step explanation:
Supplementary = angles that make up 180 degrees
We know <A and <B are supplemntary, so 2x+28+6x+72 = 180.
8x + 100 = 180
8x = 80
x = 10
I input 10 into the equations to solve for the measures of the angles
Answer: 84
Step-by-step explanation:
The total number of the questions is 9
Possible question is 3
This is combination
Therefore n=9 and r=3
Combination formula=n! / ((n-r)! r!)
9C3=9! /((9-3)! 3!)
=362880 /(6! 3!)
=362880/4320
=84
the answer is B 180
Step-by-step explanation:
if you take the triangle from the bottom and put it on the top where the missing chunk is you would get a 12 by 15 rectangle Wich would give you 180
