Question

Two angles of a quadrilateral measure 55 degree each. Third angle is 140 degree. What is the measure of fourth angle?

Answer 1

Answer:

FORTH ANGLE IS 110 DEGREE

Step-by-step explanation:

LET THE FOURTH ANGLE BE X

THEREFORE

55 +55 +140 + X = 360

110 +140 +X =360

250 + X= 360

X = 360 -250

X = 110

HENCE FORTH ANGLE IS 110 DEGREE

Answer 2

Answer:

110°

Step-by-step explanation:

Given :

Two angles = 55 °

third angle = 140°

To find :

measure of fourth angle.

Solution:

let fourth angle = X

( quadrilateral = 360° )

therefore, 55+55+140+X = 360.

250+X =360 .

X = 360 - 250.

X=110°

(X=110°)
