Question

the measures of three angles of quadrilateral is 30,70 and 100.find out the measurements of fourth angle​

Answer 1

Answer:

160

Step-by-step explanation:

Let us consider, the measure of fourth angle be ‘x’

Since the sum of angles of a

quadrilateral is 360°.................

30 + 70 + 100 + x = 360°

200 + x = 360

x = 360 - 200

x = 160

Therefore, the measure of fourth angle is 160°

Answer 2

Answer:

By Angle Sum Property

30°+70°+100°+x=360°

200°+x=360°

x= 360°-200°

x= 160°

Therefore,

The fourth angle = 360°
