x = 25º, right scalene triangle

Step-by-step explanation:

The interior angles of a triangle add up to 180º.

The red square indicates the angle measure is 90º.

We are left with two other angles, x and (2x + 15).

Let's set up an equation to represent the angle measures

90 + x + (2x + 15) = 180

First, combine like terms.

90 + x + 2x + 15 = 180

105 + 3x = 180

Subtract 105 from both sides to isolate x.

3x = 75

Divide both sides by 3 to further isolate x.

x = 25º

Let's check our answer by plugging it back into our original equation.

90 + x + (2x + 15) = 180

90 + 25 + (2(25) + 15) = 180

Simplify.

90 + 25 + (50 + 15) = 180

90 + 25 + 65 = 180

115 + 65 = 180

180 = 180

Your answer is correct.

x = 25º

Now we need to classify the triangle.

As stated before, the red square indicates the angle measure is 90º. This means our triangle is a right triangle.

Because the other two angle measures are different from one another, we know that the side measures cannot be equal. This leaves us with a scalene triangle.

Your answer is: right scalene triangle
