Question

find rhe measure of unknown angle​

Answer 1

Answer:

a=120°

b=120°

c=120°

d=60°

Step-by-step explanation:

a+60°=180 (Linear Pair)

a=120°

a=b=120° (Alternate Interior angle)

d=60° (Alternate Interior angle)

c+d=180° Linear Pair)

c+60°=180°

c=120°

Have a nice day.

Pls mark me brainliest.

Answer 2

Answer:

Let the two lines be l and m respectively,

then two transversals will be O and P(by assuming) [they are even parallel ]

here d=60• (alternate interior angle)

then c= 180-60= 120•(linear pair)

Again b=c (Corresponding exterior angle) [when taking O and P as a parallel Line]

So b=120•

also a=120• (V. O. A.)

Hence we conclude,

a=120•

b=120•

c=120•

d=60•
