Question

can someone help me with these problems I don't get it very well​

Answer 1

this is my answer but you need to check with your teacher

Answer 2

Answer:

25 & 26

• Complementary angles sum to 90°

Angle:

• 90° - 47° = 43°

Find x

• 2x -3 = 43
• 2x = 46
• x = 23

27 & 28

• Vertical angles are congruent

Angle

• 82°

Find y

• 5y + 12 = 82
• 5y = 70
• y = 14

29 & 30

• Adjacent angles forming a straight line are supplementary and sum to 180°

Angle:

• 180° - 115° = 65°

Find n:

• 4n - 5 = 65
• 4n = 70
• n = 17.5

31 & 32

Angle addition postulate

• ∠XYZ = ∠XYW + ∠WYZ

Angle

• m∠XYW = 110° - 72° = 38°

Find x:

• 3x + 2 = 38
• 3x = 36
• x = 12

33 & 34

• Complementary and vertical angles (mentioned above)

Angle

• 90° - 35° = 55°

Find n:

• 5n = 55
• n = 11
