Question

Find the value of x for whichA.31B.43C.121D.47

Answer 1

Answer:

The value of x is 31°

Step-by-step explanation:

As we can see, the two angles at the bottom of the shape are base angles. These angles both form right angles which means they both have a measurement of 90°. Knowing this information, we can set up an equation to solve for x.

47 + (x + 12) = 90

47 + x + 12 = 90

Add 12 to 47.

59 + x = 90

Subtract 59 on both sides of the equation.

x = 31

The value of x is equal to 31.
