Question

A quedrilateral has three acute angles each measuring 75°.find the measur to the fourth angle.

Answer 1

Answer:135

Step-by-step explanation:

Angle sum of quadrilateral=360degree

Let the 4th angle be x.

75+75+75+x=360

225+x=360

x=360-225

x=135 degrees

Answer 2

measure of 4th angle=

360-(75×3)

360-225=

${135}^0$
