Question

the sum of two opposite angles of a quadrilateral is 280 degrees. the other two angles are equal. find the measure of the equal angles?

Answer 1

Answer:

measure of each equal angle is 40°

Step-by-step explanation:

The sum of all angles of a quadrilateral is always 360°

If one of the equal angles is x, the sum of all the angles can be represented as

280°+2x=360°

2x=80°

x=40°

measure of each equal angle is 40°

Answer 2

ĂŃŚŴĔŔ

Let the measure of the other 2 angles be x

So, x + x + 280 = 360° (angle sum property)

2x + 280 = 360°

2x = 360° - 280°

2x = 80

x = 80/2 = 40

therefore, x = 40°
