Question

In a quadrilateral the sum of three
angles is equal to twice the
fourth.Find the measure of the
fourth angle in degrees.

Answer 1

Answer:

110°

Step-by-step explanation:

we know that the sum of the angles of a quadrilateral is 360°. x = (360-250) = 110.

Hence the measure of fourth angle is 110°

Answer 2

Answer:

120

step by step explanation:

Given,

x+y+z=2w....(i)

And we also know that

x+y+z+w=360

According to eq...(i)

(2w)+w=360

3w=360

now,

w=360/3

w=120

so,the fourth angle is 120°.
