Question

quadrilateral has three acute angles. If each measures 75°, then what is the measure of fourth angle?

Answer 1

Answer:

135°

Step-by-step explanation:

Sum of angles of a Quadrilateral = 360°

Sum of 3 acute angles = 75 + 75 + 75 = 225°

Fourth angle = 360 - 225 = 135°

Hope it helps !!!!

Answer 2

Step-by-step explanation:

We know that sum of interior angle of quadrilateral is 360.

Let the measure of the fourth angle be X. Then,

75+75+75+X =360

225+X =360

X= 360-225

X = 135
