Answer 1

Question:

A quadrilateral has three acute angles. If each measures 80°, then measure of the fourth angle is _______

Answer:

The measure of fourth angle is 120°

Explanation:

Measure of three angle of triangle is 180°

Like that,

Measure of all (four) angles of quadrilateral is 360°

As per the condition,

Each angle is 80°

Sum of the angles = 360°

80 + 80 + 80 + x = 360°

240 + x = 360°

x = 360 - 240

x = 120°

So, the measure of the fourth angle is 120°
