Question

In a quadrilateral, each of two angles has a measure of 115. If the measure of the third angle is 70, what is the measure of the remaining angle?

Answer 1

Step-by-step explanation

We are asked to find the remaining angle in the quadrilateral

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.

If the given angles are: 115, 115, and 70

Then we can get the fourth angle as folllow:

`Total\text{ angle in a quadrilateral is 360 degrees}`

Thus, the fourth angle will be

`115+115+70+x=360`

Solving for x

`x=360-115-115-70=60^0`

Therefore, the remaining angle is 60 degrees
