Question

15)Angle of the Quadrilateral are
5(x + 2)°. (4x). (7x – 20) and 6(x+3) Find the value of x​

Answer 1

Answer:

x=16

Step-by-step explanation:

5(x+2) + (4x) + (7x - 20) + 6(x+3)=360

(5x+ 10) + (4x) + (7x-20) + (6x+18)=360

(5x + 4x + 7x + 6x) + (10 + 18 - 20)=360

22x + 8= 360

22x= 360-8

22x=352

×=352 ÷ 22

×= 16
