Question

Angle A=3x-10 Angle C=45 Angle D=2x+10
Please solve for x

Answer 1

27°

Explanation:

Step 1:

∠A + ∠C + ∠D = 180° Sum of a Δ

Step 2:

3x - 10 + 45 + 2x + 10 = 180 Input all values

Step 3:

5x + 45° = 180° Combine Like Terms

Step 4:

5x = 135° Subtract 45° on both sides

Step 5:

x = 135° ÷ 5 Divide

Answer:

x = 27°
