Answer:
d = 90°
e = 41°
f = 139°
Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)
-> f = 180° - 41°
-> f = 139°
Answer:
The first statement is incorrect. They have to be complementary.
Step-by-step explanation:
You can't say the measure of angle B is congruent to theta because it is possible for angles in a right triangle to be different.
You can only say that what he said is true if the angle was 45 degrees, but based on the information provided it is not possible to figure that out.
The other two angles other than the right angle in a right triangle have to add up to 90 degrees, which is the definition of what it means for two angles to be complementary. A is the correct answer.

Answer:
That is a parallelogram so that opposite angles are equal.
10x -27 = 2x + 29
x = 7
and therefore those angles equal 43 degrees each
It is a parallelogram, so
angle V + W +X + Z = 360
we know that angle Y + angle W = 2 * 43 = 86 degrees
angle V + angle X = 360 -86 degrees
angle V + angle X = 274 degrees
angle V = 274 / 2 = 137 degrees
