Question

A quadrilateral has three acute angles each measuring 70 degrees . The measure of fourth angle is

Answer 1

As sum of the angles of a quadrilateral is 360,4th angle_360-(70+70+70)=150

Answer 2

Heya....

Three acute angle measures 70° each
So let the angle a, b and c be 70° and d= x
Sum of quadrilateral = 360°
Thus a+b+c+d = 360°
70+70+70+d= 360°
210 + d = 360°
d = 360-210
d = 150
Thus the fourth angle = 150°
