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.
