Question

If three angles of a quadrilateral 1 point
are each equal to 75°, then, the
fourth angle is
O 45
O 75
O 135%
O 150​

Answer 1

Answer:

$75 + 75 + 75 + x = 360 \\ \\ = > 225 + x = 360 \\ \\ = > x = 360 - 225 = 135$

HENCE FOURTH ANGLE IS 135°.

Answer 2

Answer:

135°

Step-by-step explanation:

We know that the sum of the angles of a quadrilateral is 360° (According to the Angle Sum Property).

Given that, ∠1 = ∠2 = ∠3 = 75°

So, By Angle Sum Property, 3(75°) + ∠4 = 360°

⇒ ∠4 = 360° - 225° = 135°
