Question

If the measure of the 3 angles of a quadrilateral are 85degree, 70degree, 100degree then the measure of 4th angle is ??

Answer 1

Answer:

In a qiadrilateral the sum of all angles will be = 360

Than ,85 +70 + 100 = 255

So , 360 - 255 = 105

So the angle = 105

Step-by-step explanation:

Answer 2

As, we know that the sum of all four angles in quadrilaterals will = 360°

let's take the fourth angle as 'x'

85 + 70 + 100 + x = 360

255 + x = 360

x = 360-255

x = 105°

∴ The fourth angle is 105°.
