What is the value of x in this figure?

X = 68°

Step-by-step explanation:

First every angle equal 180°

Take 47° + 65°= 112°

180°- 112°= 68°

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

not sure but it may be b, as i said i'm not sure.
