Question

the measuse of three angle of qudrilateral are in 5;4;2 and fourth angle is 30 there for the measuse of greateris( )​

Answer 1

Answer:

• The first angle = 150°
• second angle  = 120°
• Third angle  = 60°
• And fourth angle = 30°
• So, the measure of the greater angle is 150°.

Step-by-step explanation:

If the common multiple is x

then the first angle= 5x

second angle = 4x

Third angle = 2x

And fourth angle = 30°

We know that sum of angle of quadrilateral is 360°.

So, 5x + 4x + 2x + 30° = 360°

(5 + 4+ 2) x = 360° - 30°

11x = 330°

x = 330/11

x = 30

So, the first angle= 5(30) = 150°

second angle = 4(30) = 120°

Third angle = 2(30) = 60°

And fourth angle = 30°
