Answer 1

Answer:

Angle addition postulate

Q1

• m∠FDE + m∠CDE = m∠FDC
• 2x + 5° + 10x - 3° = 62°
• 12x = 60°
• x = 5°

• m∠FDE = 2*5° + 5° = 15°
• m∠CDE = 10*5° - 3° = 47°

Correct choice is D

Q2

• m∠BOC + m∠COD = m∠BOD
• 26° + 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)
