To find the value of x, we need to determine the measure of the missing angle in the triangle.
Since the sum of the angles in a triangle is always 180°, we can use the equation:
x + 54° + missing angle = 180°
Therefore, the equation that can be used to find the value of x is:
x + missing angle = 180° - 54°
or
x + missing angle = 126°
The measure of the 2 angles in the triangle are shown in the diagram 54°. Which equation can be used to find the value of x
