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

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
