Need answer thank u

Answer 1

Answer:

8 units

Step-by-step explanation:

In a 45°- 45°- 90° triangle the legs are congruent, thus

3x - 10 = x + 2 ( subtract x from both sides )

2x - 10 = 2 ( add 10 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Thus

3x - 10 = 3(6) - 10 = 18 - 10 = 8

Since legs are congruent then they are both 8 units
