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

SOMEONE HELP !!! Please
Lelu [443]

Answer:

x = ± \sqrt{8} - 2

Step-by-step explanation:

x² + 4x = 4

to complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 4 + 4

(x + 2)² = 8 ( take square root of both sides )

x + 2 = ± \sqrt{8} ( subtract 2 from both sides )

x = ± \sqrt{8} - 2
