Question

If the angles of a quadrilateral are
(3x-5). (8x-15), (2x+4), and (2x+16) then the value of x is​

Answer 1

Answer:

hope it helps you

Step-by-step explanation:

we know that,

sum of all angles of a quadrilateral=360°

so,

(3x-5)+(8x-15)+(2x+4)+(2x+16)=360°

or, 3x-5+8x-15+2x+4+2x+16=360°

or,3x+8x+2x+2x-5-15+4+16=360°

or,15x-20+20=360°

or,15x=360°

or,15x=360°

or, x=360°/15

therefore, x=24
