Question

Two angle of aqudrilateral measure 55dgree each. the third angle is 140 degree. What is the measure fourth angle?

Answer 1

Answer:

measure of 4th angle is 110°

Step-by-step explanation:

as sum of total interior angles of a quadrilateral is 360° then

let x = 4th angle

therfore, 55 + 55 + 140 + x = 360

again, 250 + x = 360

therefore answer is

x = 360 - 250

= 110°(Answer)

hope this helps.
