Answer:
90°, 78°, 12°
Step-by-step explanation:
let the third angle be x then the second angle is 7x - 6
Since 1 of the angles in the triangle is 90° then the second and third angles sum to 90° , then
x + 7x - 6 = 90
8x - 6 = 90 ( add 6 to both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Then
second angle = 7x - 6 = 7(12) - 6 = 84 - 6 = 78°
The 3 angles are 90°, 78°, 12°

1. This is one confusing question... But here is what I did
x = 2y + 1
y =

+ 2x
So plug in Y to solve for X
x = 2 (

+ 2x) + 1
x =
- 
Not sure if that's completely correct, but I'm positive I didn't make any mistakes...
