In the triangle ABE
step 1
Find out the measure of angle AEB
m by form a linear pair
mm
step 2
Find out the measure of angle ABE
m by alternate interior angles
step 3
Find out the measure of angle x
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
msubstitute given values
x+100+30=180
x=180-130
<h2>x=50 degrees</h2>
Answer:
87.5%
Step-by-step explanation:
to write a percentage as a number you move the decimal to the left 2 times.
The third one.
Because the answer of the absulate value equations is always positive.

; where a = 1, b = -4 and c = 8
