Answer 1

Answer:

See explanation

Step-by-step 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
