Question

Find the value of x
76
(2x+4)
A1 32
B) 5
C) 50
D)40

Answer 1

Answer is C) x = 50

Step by step

We know the straight angle will equal to 180 degrees.

We know the straight angle includes two angles (76) and (2x + 4)

So our equation is 76 + 2x + 4 = 180

Combine like terms

80 + 2x = 180

Subtract 80 from both sides to isolate variable

80 - 80 + 2x = 180 - 80

Combine like terms

2x = 100

Divide both sides by 2 to solve

2/2 x = 100/2

x = 50
