50 points! Mhanifa please help! I keep asking and you dont answer lots of them. I will mark brainliest! Random answers will be reported

Angle addition postulate

Q1m∠FDE + m∠CDE = m∠FDC2x + 5° + 10x - 3° = 62°12x = 60°x = 5°m∠FDE = 2*5° + 5° = 15°m∠CDE = 10*5° - 3° = 47°

Correct choice is D

Q2m∠BOC + m∠COD = m∠BOD26° + m∠COD = 46°m∠COD = 46° - 26°m∠COD = 20°Q3

Midpoint is equidistant from the endpoints

Given points:

M(-2, 7), A(5, 3), B(x, y)

Use midpoint formula:

(x + 5)/2 = -2 ⇒ x + 5 = -4 ⇒ x = -9(y + 3)/2 = 7 ⇒ y + 3 = 14 ⇒ y = 11

Point B is (-9, 11)

Here are the answers to the ones that i could see.
