The three inside angles of a triangle need to equal 180 degrees.
To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
Answer:
paper
Step-by-step explanation:
First, distribute the 12
156-168-15=16+4+x
-27=20+x
-47=x
Answer:
45
Step-by-step explanation:
Together, these two angles form a flat line which is 180 degrees
(x + 7) + (4x - 52) = 180
5x - 45 = 180
+ 45 + 45
5x = 225
x = 45
this is what would make sence for me
the frist one was confusing
