Question

1) the ratio of the measure of the angle of a quadrilateral is 1 is to 2 is to 3 is to 4 what is the
measure of the greatest angle

a)90 b)108 c)144 d)180

​

Answer 1

Answer:

c)144

Step-by-step explanation:

let the angles be x

then: 1:2:3:4=1x+2x+3x+4x

the measure of all sides of a quadrilateral is 360°

10x=360°

x=360/10

x=36

1x=1*36=36°

2x=2*36=72°

3x=3*36=108°

4x=4*36=144°
