Answer 1

Answer:

∠B=∠D=120°

Step-by-step explanation:

HII MATE,

THE GIVEN FIG. IS A KITE

SO, IN KITE ONE PAIR OF OPPOSITE ANGLES ARE EQUAL.

AND WE CAN SEE THAT, ∠A≠∠C

SO,∠B=∠D

TOTAL SUM OF ANGLES,

∠A+∠B+∠C+∠D=360°

=>80°+∠B+40°+∠D=360°

=>∠B+∠D=360°-120°=240°

=>2∠B=240°   (SINCE ∠B=∠D)

=>∠B=∠D=120°
