Question

pls tell me the answer ​

Answer 1

Answer:

the answer is 60°

Step-by-step explanation:

we know that sum of all angles of a quadrilateral is 360°

so,(X+20)+(x-20)+(2x+5)+(2x-5)=360°

X+X+2x+2x=360°

6x=360°

X=60°

hope it helps you

Answer 2

Step-by-step explanation:

we know that,

sum of all angles of quadrilateral = 360°

(x + 20) + (x-20) + (2x+5) + (2x - 5) = 360°

x + 20 + x -20 + 2x + 5 +2x -5 = 360°

x + x + 2x + 2x = 360°

6x = 360°

x = 360° / 6

x = 60
