Can someone help please!

1. B. <1 and <2

2. C. 37°

3. B. 40°

Step-by-step explanation:

1. Complementary angles add up to 90°.

From the diagram given, <1 and <2 are complementary because they sum up to 90°.

The answer is B. <1 and <2

2. Given that,

m<1 = 37°, m<4 = 37° also.

This is because m<1 and m<4 are Vertical angles. Vertical angles pair are equal.

The answer is: C. 37°

3. If m<1 = 50°, then:

m<5 = 90 - m<4

m<1 = m<4 = 50° (vertical angles)

m<5 = 90 - 50 (substitution)

m<5 = 40°

Answer is B. 40°
