Question

Two angles of a quadrilateral are of measure 50 * , and the other two angles are equal. What is the measure of each of these two angles?

Answer 1

50+50+a+a=360
2a=260
a=130

Answer 2

hey dude

according to the question,
two angles of quadrilateral measures 50°
and the other two angles are equal

then,

let the other two angles of quadrilateral be x
sum of all angles of quadrilateral=360°

50°+50°+x+x=360
100°+2x=360°
2x=360°-100°
2x=260°
x=260°÷2
x=130°

the other two angles measure 130°

hence,°
first angle is 50°
second angle is 50°
third angle is 130°
fourth angle is 130°
