Can someone explain to me how to do

A straight line is 180°, so you can do this:

118 + y = 180

y = 62°

The triangle is an isosceles triangle, so the other angle of the triangle is 62° too.

Now that you have 2 of the 3 angles, you can go find the 3rd angle.

62 + 62 + z = 180

z = 56°

Now you can go find ∠2

56 + ∠2 = 180

∠2 = 124°

124 = 12x + 4

120 = 12x

10 = x

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

i think 1: 2
