Question

please answer q.no 1.and 2.​

Answer 1

Step-by-step explanation:

hlo mate.....

1. angle B =angleBCD.=64(Alternate triangle)

In triangle ABC ...64 +72+angle ACB =180.

ANGLE ACB=180-136=44.

AND NOW..44 +64+ Y =180( LINEAR PAIR)

Y=180-108=72.....

2.In triangle A B C.. 63+57+angle ACB =180...

angleACB=180-120=60..

Y =ANGLE B (ALTERNATE ANGLE)=63..

NOW 63+60 +X=180(LINEAR PAIR)

X=180-123=57...

Answer 2

Step-by-step explanation:

(i) x=∠ABC=64°(Alternate Interior Angles)

   x+y+(180°-72°-64°)=180°

   x+y+44°=180°

   64°+44°+y=180°

   y=180°-108°=72°

(ii) y=63°

  ∠c=180°-57°-63°=60°

  x+y+∠c=180°

  x+63°+60°=180°

   x=180°-123°=57°
