Answer:
(C) x = 56
Explanation:
To find the value of x, we first need to find the measure of its supplement, or the angle which, when added to x°, results in 180°, or a straight line.
We can find the measure of its supplement by using the fact that the measures of the interior angles of a triangle add to 180°.
Hence, we can form the following equation to solve for the measure of the supplement.
37° + 19° + s° = 180°
s° = 124°
Now, we can subtract the measure of the supplement from 180° to get x°.
x° = 180° - 124°
x° = 56°
We can cancel the degrees on both sides of this equation to solve for x.
(C) x = 56
