Geometry help please explain

Answer:
x = 25
Step-by-step explanation:
The sum of the angles of a triangle add to 180
We have a right triangle so one of the angles is 90degrees
90 + 2x + x+ 15 = 180
Combine like terms
105+3x = 180
Subtract 105 from each side
105+3x-105 = 180-105
3x = 75
Divide by 3
3x/3 = 75/3
x = 25
Answer:
So the inside of a triangle will equal 180 degrees so, you would set up your equation as 90+2x+(x+15)= 180
you then solve that equation let me know if you didn't get the equation solved.
