Question

.Two adjacent angles in a parallelogram are in the ratio 2:4. Find the values. *

60 degrees, 120 degrees
20 degrees, 40 degrees
30 degrees, 120 degrees
none of these

Answer 1

Answer:

Answer

The sum of 2 adjacent angles of a parallelogram is 180 degrees.

Let the angles are x and 2x.

∴x + 2x =180

o

∴3x=180

∴x=60

o

Hence angles are x=60

o

and 2x=120

◕➜ Option A. 60° & 120°

____________________

☞ Adjacent Angles of Parallelogram are Supplementary (180°)

Given,

Ratio of Adjacent Angles = 2:4

Let, Angle 1 = 2x° & Angle 2 = 4x°

→ 2x°+4x° = 180°

→ 6x° = 180°

→ x° = 180°÷6

➝ x° = 30°

Angle 1 = 2x° => 60°

Angle 2 = 4x° => 120°
