Question #6

The SUM of the angles in the parallelogram below is 360°, what is the value of x?
(5x)
(3x + 4)
(3x + 4)
(5x)
A
x = 23
B.
x = 15
I
С
x = 22
D
x = 21

Answer 1

x = 22

Explanation:

Add the expressions for the angle measures.

5x + (3x + 4) + (3x + 4) + 5x = 360

Combine like terms.

16x + 8 = 360

Subtract 8.

16x = 352

Divide by 16.

x = 22

Answer 2

22⁰

Explanation:

5x + 3x + 4 + 3x + 4 + 5x = 360⁰

=> 16x + 8 = 360

=> 16x = 360 - 8

=> 16x = 352

=> x = 352/16

=> x = 22

Hence,

Value of x is 22⁰
