Question

Three angles of a quadrilateral measure 68,74and 108 respectively.find the measure of the fourth angle

Answer 1

360-(68+74+108)=110

Step-by-step explanation:

we know sum of all angles of quadrilateral is 360°

So,

A+B+C+D=360°

68+74+108+D=360

250+D=360

D=360-250

D=110°

Answer 2

The sum of the interior angles of any quadrilateral is 360°

Question:

Three angles of a quadrilateral measure 68, 74and 108 respectively. Find the measure of the fourth angle.

Equation:

$360 - (68+74+108) =$

Solution:

$=360 - (68+74+108) \\=360 - 250 \\=110$

Answer:

The measurement of the fourth angle is 110°.
