Answer:
90deg
Step-by-step explanation:
If the angles are supplementary, that means mA + mB = 180*
we know that
mA = (2x + 8)deg
mB = (2x + 8)deg = mA
mA + mB = 180deg
mB + mB = 2mB = 180deg
mB = 90deg
Note, that we did not need to compute x even, because the angles were the same.
Answer:
The correct answer is C. 13
Step-by-step explanation:
It is 13 because all triangles equal 180
so 125+42+13=180
The sequence is given by (n+5)²
For n=100:
(100+5)² = 105² = 11025
