## KE8717504 3 years ago Solve using matrices. In a triangular cross section of a roof, the largest angle is 100 degrees greater than the smallest angle. The largest angle is 80 degrees greater than the reamining angle. Find the measure of each angle. The smallest angle = ____ degrees

1. alanli123

hint use gaussian elimination method

2. KE8717504

I have no idea what that is or how to use it?

3. KE8717504

I need someone to help me by walking me through the steps

Solve using matrices. In a triangular cross section of a roof, the largest angle is 100 degrees greater than the smallest angle. The largest angle is 80 degrees greater than the reamining angle. Find the measure of each angle. z=100+x z=80+y x+y+z=180

14. Agent47

wait friend needs help again

15. Agent47

-1x+0y+z=100 0x-1y+z =80 1x+1y+1z=180
