The answer is 35/10 and 6/10
To find angle c, the fourmula is 1/2 of the intercepted arc. so, this would be (-3x-6)=(-4x)/2, then bring the 2 over, (-3x-6)2=-4x, multiply the 2, -6x-12=-4x, -2x=12, simplify, x=-6
check by plugging in.

- d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.
In our case :

A leg of a right triangle can never be greater then the hypotenuse
this formula will tell you if it's a valid right triangle

the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.
