x = 25 degrees
Step-by-step explanation:
All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.
180 = 99 + 56 + x
180 = 155 + x
25 = x
The unknown angle is equal to 25 degrees.
Answer:
d) 
Step-by-step explanation:
we simplify 
by doing 7 x 2 = 14
so it is now
to check, we can use a calculator.
7 to the power of 14 = 678223072849
and
7 to the power of 7, squared also = 678223072849
Hope this helps!
