Question

A quadrilateral has three actute angles each measuring ${70}^0$, what is the measure of the fourth angle?

Answer 1

sum of all 4 angles in a quadrilateral is ${360}^{\circ }$

3angles=${70}^{\circ }$

So, fourth angle=${360}^{\circ }-{70}^{\circ }-{70}^{\circ }-{70}^{\circ }={150}^{\circ }$
