Question

2. The measures of adjacent angles of a parallelogram are x and 2x. Find the value of x​

Answer 1

Answer:

x = 20⁰

Step-by-step explanation:

we know that the sum of adjacent angled of a parallelogram is 180 degree

( 2x + 25 ) ⁰ + ( 3x - 5 ) ⁰ = 180 ⁰

5x + 20 = 180⁰

5x = 180⁰- 20⁰

5x = 160⁰

x = 160⁰/5 = 32⁰

Answer 2

Answer:

x=120°,360°=240°+120°.

Step-by-step explanation:

As

Step 1:

Add 2x and x.

Step 2:

The total angle° of a parallelogram is 360°

Step 3:

Then divide 3x with 360°

Step 4:(optional)

The side of two adjacent angles are 120° and (2x=) 2*120=240°

Step 5:(optional)

Total measure=240°+120°=360°
