90? there’s a 45 degree angle at the bottom left and it looks like the same angle as x and y
Answer:
so one side right?
Step-by-step explanation:
Multiply all terms by 12/1 to get rid of fractions.
8x+2= -9x+12
Add 9x to both sides
17x+2=12
Subtract 2 from both sides
17x=10
Divide both sides by 17
x=10/17
Final answer: x=10/17
Cos x=5/12. Solve for x which is 65.37 degrees.
