The little rectangle in the top right means the angle is a right angle which equals 90 degrees.
This also means all the other angles are also 90 degrees.
Solve for x:
2x+8 = 90
Subtract 8 from both sides:
2x = 82
Divide both sides by 2:
x = 82/2
x = 41
Answer:
127 degrees
Step-by-step explanation:
540 degrees is what the interior of a pentagon should add up to. So you do 540-156-72-98-87=127. The measure of the final interior angle is 127 degrees.
Loge 70.81 = a
Log to the base e is also written as ln
ln 70.81 = a
10P8 = 10!/(10 - 8)! = 10!/2! = 1,814,400
