Question

The angles of a quadrilateral are 5x ,(3x+10)(6x-20) (x + 25) (i) find the value of x and the measures of each of the angle

Answer 1

Step-by-step explanation:

Sum of all angles =360°

Hence,

5x+3x+10+6x-20+x+25=360°

15x+15=360°

15(x+1)=360°

x+1=360/15

x=24-1

x=23°

Angles =

5(23°)=115°

3(23)+10=79°

6(23°)-20=118°

23°+25=48°
