Question

Let (5x+10) represent the measure of a right angle. What is the possible value of x?

Answer 1

16

Explanation:

A right angle has the measurement of 90°. Set the expression equal to 90:

5x + 10 = 90

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 10 from both sides:

5x + 10 (-10) = 90 (-10)

5x = 90 - 10

5x = 80

Next, divide 5 from both sides:

(5x)/5 = (80)/5

x = 80/5

x = 16

16 is your possible value.
