Question

Three angles of a quadilatare are 59.40and 123 dgree find the fourth angle?

Answer 1

Answer:

138°

Explanation:

Sum of all angles of quadrilateral = 360°

Given that,

First angle = 59°

Second angle = 40°

Third angle = 123°

Let the fourth angle be x.

=> 59° + 40° + 123° + x = 360°

=> 222° + x = 360°

=> x = 360° - 222°

=> x = 138°

Hence, the fourth angle is 138°.
