Answer:
13
Step-by-step explanation:
x/y = 4
x=4y
x - y = 39
4y - y = 39
3y = 39
y= 13
A similar because all triangles add up to 180 ,
they both have 80 so leaves 100 degrees left..
and they both have the same #'s 80, 60, & 40 degrees equal to 180 degrees
Answer:
12^5
Step-by-step explanation:
12^5 means 12*12*12*12*12 (5 twelves)
as the horizontal beam are parallel to each other x and 40 are alternate angles and alternate angles are equal. So <u>x=40</u>
