Sagot :
Answer:
∠ D = 127°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ D is an exterior angle of the triangle , then
∠ D = 85° + 42° = 127°
Answer:
D = 127°
Step-by-step explanation:
We know that sum of all angles in a triangle is 180°.
Thus, the measure of third angle will be -
180 - (85 + 42)
180 - 127
= 53°
We also know that sum of adjacent angles is 180°. So,
D = 180° - third angle
D = 180° - 53°
D = 127°
