Xw Is an altitude
M Prove: x=12

Answer 1

See explanation

Explanation:

Given: XW is an altitude

m∠XWY=8x-6

Prove: x=2

Solution:

Statement Reason

1. XW is an altitude Given

2. m∠XWY = 90° Definition of altitude

3. m∠XWY = 8x - 6 Given

4. 8x - 6 = 90 Substitution property

5. 8x - 6 + 6 = 90 + 6 Addition property of equality

8x = 90

6. x = 12 Division property of equality
