Question

in a quadrilateral three angles are in the ratio 3:3:1 and forth angle 80° and find the measure of other angle ​

Answer 1

Answer:

The measure of three angles are 120°,120° and 40°.

Step-by-step explanation:

The measure of fourth angle is 80°

Let the three angles be 3x,3x and x

ATQ.

3x+3x+x+80=360

7x=360-80

X=280/7

X=40

Therefore, the angles:

3x=3×40=120°

3x=3×40=120°

X=40°

Answer 2

Answer:

Given, ratio is 3:3:1 and fourth angle is 80°. Sum of all the angles of the quadrilateral is 360°. Therefore, the four angles are 120°, 120°, 40° and 80°.
