Question

One angle of a quadrilateral is 135º and the other three angles are equal. Find the measure of the
other three angles.​

Answer 1

Answer:

75

Step-by-step explanation:

let the other 3 angles be x

x+x+x+135°=360°

3x=360-135

=225

x=225/3

=75

Answer 2

Question:

One angle of a quadrilateral is 135º and the other three angles are equal. Find the measure of the other three angles.

Answer:

Let other three angles be x

We know that sum of all side of a quadrilateral = 360°

According to the question,

135 + x + x + x = 360°

135 + 3x = 360°

3x = 360 - 135

3x = 225

x = 225 ÷ 3

x = 75°

Therefore measure of three angles is 75°.
