Answer:

x = 30

Step-by-step explanation:

We start off with 90 degrees

2x + x = 90

Add all like terms

3x = 90

Divide 3 on both sides

\frac{3x} {3} = \frac{90} {3}

x = 30

To check your answer:

Let x be 30

2x + x = 90

2 (x 30) + 30 = 90

60 + 30 = 90

90 = 90

frosja888 [35]

Hey there!:

According to the Pythagorean theorem, the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse (H):

1² + 19² = x²

1 + 361 = x²

x² = 1 + 361

x² = 362

x = √ 362

x = 19.02

Hope this helps!
