Question

If the measure of three angle of Quadrilaterl are 58°,42° and 100° the find out the measure of the fourth angle​

Answer 1

Answer:

160

Step-by-step explanation:

we know that,

sum of the angles of quadrilateral is 360degrees

so let fourth angle be a...

then a + 58 + 42 + 100 = 360

a + 200 = 360

a = 360 - 200

a = 160

Answer 2

Answer:

160

Step-by-step explanation:

Sum of all angles of quadrilateral=360

let angle 4 be x

1. 58+42+100+x=360

2. 200+x=360

3. x=360-200

4. x=160
