If m∠4 = 35, find m∠3. Explain. 145; ∠3 and ∠4 are supplementary angles, so m∠3 = 180 − m∠4.

55; ∠3 and ∠4 are complementary angles, so m∠3 = 90 − m∠4.

35; ∠3 and ∠4 are corresponding angles, so m∠3 = m∠4.

35; ∠3 and ∠4 are alternate interior angles, so m∠3 = m∠4

55; ∠3 and ∠4 are complementary angles, so m∠3 = 90 − m∠4.

Step-by-step explanation:

Complementary angles are a pair of two angles that add up to give us 90°.

Thus, angle 4 and angle 3 are complementary angles.

m∠ACD = 90°, m∠4 = 35°, therefore,

m∠ACD = m∠4 + m∠3.

Thus:

90° = 35° + m∠3

Subtract 35 from both sides

90 - 35 = 35° + m∠3 - 35

55 = m∠3

m∠3 = 55°.

rick would give her the best deal as he will charge $8.88 per hour

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
