Question

The measure of three angles of a quadrilateral is 30degree 70degree and 100degree. Find out the measurement of fourth angle ​

Answer 1

Answer:

Given- Measure of 3angles= 30°, 70°, 100°

4th Angle = ?

Step-by-step explanation:

let the 4th Angle be 'X'

As we know that angle of the quadrilateral is 360°

30°+70°+100°+X°=360°

200°+X°=360°

X°=360°-200°

X°=160°

Therefore the 4th angle is 160°
