Hello! A triangle has angles that sum up to 180°. So first off, let's solve for the angle of the other triangle. 83 + 31 gives us 114. 180 - 114 is 66. So the angle for the first triangle is 66°. The opposite angle would be the same. Finding the measurement of the other triangle gives us the measurement of x, because the angles are the same. So x = 66°.

Put like terms together:
= -9x + x = 35 + 12
= -8x = 47
= x = -47/8
= x = -5.875
In short, Your Answer would be: -5.875

Answer:
x=13,y=39
Step-by-step explanation:
y=3x,x+y=52
x+3x=52
4x=52
x=52/4
x=13
y=3(13)
y=39
Answer: y>-3 and x is all real numbers
