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
<u>Combine like terms</u>
3x + 105 = 180
<u>Subtract 105 from both sides.</u>
3x = 75
<u>Divide each side by 3.</u>
<u>x = 25</u>
<u>x is equal to 25.</u>
As for the triangle, it is a <u>right scalene triangle</u>, 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).
