Question

Angles of a quadrilateral is 1:2:2:3. What is the measure of largest angle?

Answer 1

Answer:

135 degree

Step-by-step explanation:

ratios of angles = 1:2:2:3

sum of angles of a qualdrilateral = 360 degree

1x+2x+2x+3x=360

8x=360

x=45

Largest angle=3*45= 135 degree

Answer 2

Answer:

let the angles be 1x,2x,2x,3x

w.k.t.sum of angles of a quadrilateral=360

1x+2x+2x+3x=360

8x=360

x=360/8

x=45

2x=2×45=90

2x=2×45=90

3x=3×45=135

so the largest angle is 135°
