Question

pls ans the question step by step​

Answer 1

Answer:4x+5x+4x+5x=360

On solving

18x=360

X=20

So 4x=

4*20=80

5*20=100

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Measure of all angles of quadrilateral is 360°

Therefore,

4x+5x+4x+5x=360°

18x=360°

x=360/18

x=20.

Now,

first angle=4x=4×20=80

second angle=5x=5×20=100

third angle=4x=4×20=80

fourth angle=5x=5×20=100
