Help me plz is for math

[ Answer(s) ]

[ Explanation(s) ]

- Problem One -

The angle with the square equals 90°.

25 + X = 90 Degrees.

To find X, we need to use subtraction.

90 - 25 = 65.

The missing angle is 65, but now we need to figure out how to get 65.

Equation: 3x + 11 = 65

Subtract 11 From Both Sides:

3x + 11 - 11 = 65 - 11

Simplify:

3x = 54

Divide Both Sides By 3:

=

Simplify:

Check your work: 3 * 18 + 11 = 65

- Problem Two -

The angle that has 3x equals 180°.

To find what X equals, we need to use subtraction.

180 - 45 = 135. Now we need to find the answer to the equation:

3x = 135

Divide Both Sides By 3:

=

Simplify:

Check your work: 3 * 45 = 135
