We are able to set 4x+32 equal to 6x-8 because these are congruent vertical angles

4x+32=6x-8
4x+40=6x (add 8 to both sides)
40=2x (subtract 4x from both sides)
X=20 (divide both sides by 2)

Then we plug in 20 for x into 6x-8 to find the answer

6(20)-8
=120-8
=112

Hope this helps!

Angle BEC = angle AED

Vertically opposite angles are equal

6x - 8 = 4x + 32
6x - 4x = 32 + 8
2x = 40
x = 20

angle BEC = 6 x 20 - 8 = 112°

Please answer correctly<br><br> 2 + 3( 4x + 5) = -53

andre [41]

Answer:

x=-35/6

Step-by-step explanation:

2 + 3( 4x + 5) = -53

subtract 2 from both sides= 3(4x+5)=-55

divide both sides by 3 = 4x+5=-55/3

subtract both sides by 5 = 4x=-70/3

divide both sides by 4 = x=-35/6

x=-35/6 is your final answer
