Question

The sum of two angles of a quadrilateral is 210°. the two angles are equal. Find the measure of each angle.​

Answer 1

Answer:

given

• sum of two angles is 210
• other 2 angles are equal

Step-by-step explanation:

let the other 2 angles be x so 2x

• 2x+210=360
• 2x=360-210
• 2x=150
• x=150/2
• x=75

so the measure of angle x is 75

Answer 2

Answer:

Given:

1. Sum of two angles of a quadrilateral=210°

2. The given two angles are equal.

Solution:

Let that two angles be x and y.

But it is given that, two angles are equal.

Therefore,

x=x

Therefore, as per given condition,

x+x=210°

→2x=210°

→x=210°/2

→x= 105°

Therefore, measure of each angle is 105°.
