Question

the four angles of a quadrilateral are as 3:5:7:9.find measures of all its angles

Answer 1

Step-by-step explanation:

3x+5x+7x+9x=360

24x=360

x=360by 24

x=15 Then,

first angle=3 into 15=45

second angle =5 into 15=75

third angle=7 into 15=105

fourth angle =9 into 15=135

so , four angles are 45,75,105,135
