No, because simplified, 20/28 would be 5/7, not 3/4
21/28 would be equivalent to 3/4 though
<span>We simplify the equation to the form, which is simple to understand
<span>4x+8-2x=20
We move all terms containing x to the left and all other terms to the right.
<span>+4x-2x=+20-8
We simplify left and right side of the equation.
<span>+2x=+12
We divide both sides of the equation by 2 to get x.
<span>x=6</span></span></span></span></span>
Answer:
17°
Step-by-step explanation:
ΔXWZ = ΔYWZ (they are congruent triangles so ∠XWZ = ∠YWZ)
5x - 8 = 9x - 28
Rearrange and collect the like terms
-8 + 28 = 9x - 5x
20 = 4x
x = 5°
∠YWZ = 9x - 28
sub x = 5
= 45 - 28
= 17°
