To answer this you need to use the Pythagorean theorem, the first part it 4^2+x^2=7^2 so the answer to the bottom x is 5.7. Your next step is to do the Pythagorean theorem for the whole triangle so your equation would be 10^2 + 5.7^2= x^2 once you solve that you will get 132.49 which you need to take the square root of. Once you will do that you will find the other x = 11.5
2x+15 = 3x-25
2x-3x = -25 -15
-x = -40
x = 40
Angle 2 = 22 degrees (that line is dividing that angle into 1 & 2 equivalently)
Angle 3 = 90 degrees.
Answer: B
Step-by-step explanation:
Hi there
9a + 3(8-2a)
9a + 24 - 6a
(9a -6a) +24
3x + 24
I hope that's help !
