Question

The angles of quadrilateral
are 6x (2x+15), (6x- 20) and
(x+20) Find value of x
and measure of angle
the quadrilateral​

Answer 1

Step-by-step explanation:

Sum of angles of a quadilateral is 360  

5x+3x+10+6x-20+x+25=360  

 

15x+15=360 360

15x=360-15=345 345

x=345/15 23

x=23  

The angles are:  

5x= 5*23=115 115

3x+10= (3*23)+10=79 79

6x-20=(6*23)-20+118 118

x+25=23+25=48 48
