60x - 12 = 14x^2 + 14x
Subtract 60x & Combine
-12 = 14x^2+14x-60x
-12= 14x^2-46x
Add 12
0= 14x^2-46x-14
The answer is C. 90 degrees.
This is because angle R is one of the four angles of a square.
I hope this helps.

Answer:
Undefined
<em>Step </em><em>by</em><em> step</em><em> </em><em>explaination:</em>
<em> </em>
by order of operations we know that we multiply first;
so, 0x-(7*9)=0
1) Multiply the ones in brackets first:
0x-63=0
2) To make X the subject perform the opposite operation:
0x-64+63=0+63
0x=63
3) Divide 0 on both sides;
0x/0= 63/0
therefore; <u>x is undefined</u>
