Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
it is c {-2,-1,2,5} lmk if it is wrong
You can find the answer by plugging in any of the multiple choice options into a,
when you square a number (^2), the result is always positive even if the number starts off negative,
-25 or 125 wouldn't work for this equation because the answer is too big
but when you plug -5 or 5 in you get the right answer, so the answer is c
