Question

then x=

pls ans this it's very important ​

Answer 1

Answer:

42.5

Step-by-step explanation:

x+5+3x+5=180°(because it is a quadrilateral and sum of opposite sides of a quadrilateral add up to 180°)

4x+10=180°

4x=180°-10

4x=170°

x=170°/4

x=42.5°

Answer 2

3x+5= ---} 1

x+5 = ---} 2

from equation 1 and 2

x+5+3x+5=180⁰

4x+10=180⁰

4x=180-10

4x=170⁰

x=170 / 4

x = 42.5

here x=42.5

3x+5 = 3(42.5)+5

= 127.5 + 5

= 132.5

x+5 = 42.5 + 5

= 47.5

hope it helps
