Question

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

Answer 1

The fourth angles measures 150 degrees.As the sum of all angles in a quadrilateral is 360 degree.Since there are 3 angles measures 70 degrees.So 4th angle measures=360-210=150 degrees.

Answer 2

a quadrilateral have angle of 70° each of 3 .

therefore , as we know that the sum of all angle of a quadrilateral is = 360

let fouth angle be x

therefore , 70 ° + 70 ° + 70 ° + x = 360 °

therefore, 210°+ x = 360 °

=> x = 150 °

hence , fouth angle is => 150 °

hope it helps!!
