Answer 2

Answer:

85

Step-by-step explanation:

sum of angles of a quadrilateral is 360⁰

x+x+3+x+8+x+9=360(add like terms)

4x+20=360(transport 20 so + become-)

4x=360-20

4x=340(transport 4 × become÷)

x=340/4

x=85

(substitute the value of x in its place)

1st angle=85⁰

2nd angle=85+3=88⁰

3rd angle=85+8=93⁰

4th angle=85+9=94⁰

therefore the angles of the given quadrilateral is 85⁰,88⁰,93⁰,94⁰
