Final answer:
To find the measure of the missing angles, we need to use the fact that the sum of angles in a triangle is 180°. By setting up an equation with the given angles, we can solve for the missing angle.
Step-by-step explanation:
To find the measure of the missing angles, we need to use the given information. Let's analyze the given values:
Since d is missing, we can use the fact that the sum of angles in a triangle is 180°. We can set up an equation to find the missing angle:
106° + d + 54° = 180°
Simplifying the equation, we get:
d = 180° - 106° - 54°
d = 20°
So, the measure of the missing angle d is 20°.
