parallelogram 'best ' is given below. find the measurement of angle X and angle Y .​

Answer 1

Answer:

X= 100°

Y= 100°

This is absolutely correct, I did it.

mark as brainliest.... peace :)

Answer 2

Here,

∠X = ∠Y

[Since BE || TS and X and Y are corresponding angles.]

We know,

Sum opposite angles of a ||gm = 180°

∴ ∠BTS + X = 180°

→ 100° + X = 180°

→ X = 180° - 100°

→ X = 80°

∴ ∠X = ∠Y = 80° (Answer).
