So the question says...

Suppose you have ∠SMB and m ∠SMB =125.35 °.

Part A: Determine the angle measure that is complement to ∠SMB, if possible. If ∠SMB does not have a complementary angle, then explain why it does not.

Part B: Determine the angle measure of the supplement of ∠SMB.

Part C: Determine the angle measure of the angle complement to ∠SMB’s supplement.

I’m stuck on this question so if anyone can help me with it that would be greatly appreciated. Thanks!

Respuesta :

Part A. Two angles are complementary if their sum is equal to 90°. Since the angle given is more than 90°, there is no possible complement for a 125.35-degree angle.

Part B. Two angles are supplementary if their sum is equal to 180°. So,
Supplementary angle = 180 - 125.35 = 54.65°

Part C. Complementary angle = 90 - 54.65 = 35.35°

Part A: ∠SMB does not have a complementary angle

Part B: The angle measure of the supplement of ∠SMB is 54.65°

Part C: The angle measure of the angle complement to ∠SMB's supplement is  35.35°

The given angle is ∠SMB and m ∠SMB =125.35 °

  • For Part A

Complementary angles are angles that sum up to 90°.

To determine the angle measure that is complement to  ∠SMB, we will find the angles that adds up to ∠SMB to give 90°. Since  ∠SMB is already greater than  90°, therefore,  ∠SMB does not have a complementary angle.

  • For Part B.

Supplementary angles are angles that sum up to 180°.

To determine the angle measure of the supplement of ∠SMB, we will find the angle that adds up to ∠SMB to give 180°. Let the measure of the angle be x, that is

x + 125.35° = 180°

∴ x = 180° - 125.35°

x = 54.65°

∴ The angle measure of the supplement of ∠SMB is 54.65°

  • For Part C

To determine the angle measure of the angle complement to ∠SMB's supplement, we will determine the measure of the angle that adds up to ∠SMB's supplement to give 90°. Let the angle be y

Then,

y + 54.65° = 90°

(NOTE: ∠SMB's supplement is 54.65°)

∴ y = 90° - 54.65°

y = 35.35°

∴ The angle measure of the angle complement to ∠SMB's supplement is  35.35°

Hence,

Part A: ∠SMB does not have a complementary angle

Part B: The angle measure of the supplement of ∠SMB is 54.65°

Part C: The angle measure of the angle complement to ∠SMB's supplement is  35.35°
