Question

In the given figure , OB and OC are bisectors of angle B and angle C , find X and Y ?

Answer 1

Answer:

X = 20

Y = 130

Step-by-step explanation:

Answer 2

Answer :

$W.K.T \: \: \: y \: = 90° \: \: + (\frac{1}{2} \times A \: )$

$=> \: y \: = 90 + ( \frac{1}{2} \times 80)$

$=> \: \: y = 90 + 40 = 130$

Therefore, y = 130°

As OC is bisector of ACB, OCB = 30°

In triangle OCB :-

y + OCB + x = 180°

=> 130° + 30° + x = 180°

=> x = 180° - 160°

=> x = 20°

Therefore, x = 20° & y = 130°
