Question

The measure of two angles of quadrilateral are 120degrees and 50degrees and other two angles are equal. Find the measure of each of the equal angle

Answer 1

$\huge\underline\mathfrak{Answer:}$

Let the two equal angles be x

Sum of angles of a quadrilateral=360°

x+x+120°+50°=360°

2x+170°=360°

2x=360-170

2x=190

x=95°

The other two angles are 95°,95°

Answer 2

$\large\mathcal\red{solution}$

let the other two angles of each is x°

now ....we know that the sum of all four interior angles of a quadrilateral is 360°

so.....

$\:120°+50°+X+X=360°\\=>170°+2x=360°\\=>2x=360°-170°\\=>X=\frac{190°}{2}\\=>X=95°\\\\so \:the\:angles\:are\:120°,50°,95°\:and\:95°$
