Question

7. Three angles of a quadrilateral are 72°, 80° and 95°, find the fourth angle.
6. State the
(a) 3 sides
• 1​

Answer 1

Step-by-step explanation:

Sum of all angles of a quadrilateral is 360°

So,

Let fourth angle be x

Now,

x + 72°+80°+95° = 360°

=> x + 247° = 360°

=> x = 113°

Answer 2

Answer: 115

Step-by-step explanation:

according to the angle sum property of a quadrilateral : summ of all interior angles is 360. Let the angle be x

So, 72 + 80 + 95 + x = 360

247 + x = 360

x = 360 - 245

x = 113
