QUESTION:- in this picture equilateral quadrilateral is given find the measurement of angle y
ANSWER:- we see quadrilateral is equal so
diagonals are equal
forms 90° at intersection
and one of the side angle is given 30°.
taking that area as Triangle .
one angle= 30°
second angle = 90° (diagonal intersection)
third angle = y
sum of all angles of triangle is 180°
30° + 90° + y = 180°
120° + y = 180°
y = 180-120
y= 60°
Hope it helps
