2 answers:
Answer:
x = 7
Step-by-step explanation:
The 2 marked angles are Alternate exterior angles ( they are outside the parallel lines ) and are congruent, that is
10x = 9x + 7 ( subtract 9x from both sides )
x = 7
Answer:
x = 7.
Angle = 70 degrees.
Step-by-step explanation:
These 2 angles are exterior alternate angles and so they are equal.
So 9x + 7 = 10x
Subtract 7 from both sides:
9x + 7 - 7 = 10x - 7
9x = 10x - 7
Subtract 10x from both sides:
9x - 10x = 10x -10x - 7
-x = -7
x = 7
The measure of the angle = 10x
= 10*7
= 70 degrees.
