I need help, I was not at school when they taught this

It is a right scalene triangle.

Step-by-step explanation:

x=25

Answer and Step-by-step explanation:

Triangles angles, when added together, equal 180 degrees.

To find x, we add everything together and equal it to 180. The red box symbolizes that the triangle is a right triangle, and right triangles have 90 degree angles as one of the angles (the red mark).

2x + 15 + x + 90 = 180

Combine like terms

3x + 105 = 180

Subtract 105 from both sides.

3x = 75

Divide each side by 3.

x = 25

x is equal to 25.

As for the triangle, it is a right scalene triangle, because it has a right angle, and the sides are all different sizes, which is what scalene means (when a triangle has different side lengths).

I hope this helps!
