Question

Three angles of quadrilateral are 30, 150 and 80°. Find the 4h angle.​

Answer 1

Answer:

we know that sum of all angles of

a quadrilateral is 360°

let the remaining angle be x

thus

30+150+80+x=360°

260+x=360°

x=360-260

x=100

therefore the remaining angle is 100°

Answer 2

Answer:

100°

Step-by-step explanation:

Given angles:-30°,150°,80°,?

Let the fourth angle be x°

We know that the sum of interior angles of quadrilateral is 360°

So here

30+150+80+x=360°

260+x=360°

x=360-260=100

Therefore fourth angle is 100
