Question

A quadrilateral has two angles that measure 70 and 60. The other two angles are in a ratio of 4:19 what are the measures of those two angles.

Answer 1

We can obtain the answer from the Angle sum property of a quadrilateral.

Angle sum property of a quadrilateral =360 degrees.

So, 70+60+4x+19x=360 degrees

130+23x=360degrees

23x=360-130,230

23x= 230 divided by 23, 10

X=10

Angles are:-

4x=4*10=40

19x=19*10=190
