Answer: 22.5 degrees
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees.
So we can set up an equation to solve for x.
x + 45 + 5x = 180.
Combine like terms of x:
6x + 45 = 180
Subtract 45 from both sides:
6x = 135
Divide both sides by 6:
x = 22.5 degrees
5/8=15/x
cross multiply and divide to find x.
8*15=120
120/5=24

There are six ten second periods in a minute, and are therefore eighteen every three minutes. 9*18 = 162 beats.
10
substitute 0 for x in the equation.
-9(0) - 2y= -20
0 - 2y = -20
-2y= -20 (divide by -2)
y = 10
Answer:
120
Interior angles have the same degree or #
