Question : 65 of 100

Marks: +1, -0

In

△ A B C, ∠ A=50^{∘}

. If the bisectors of the angle

B

and angle

C

, meet at a point

O

, then

∠ B O C

is equal to

$115^{∘}$
$50^{∘}$
$65^{∘}$
$130^{∘}$

Solution:

Given,

∠ A=50^{∘}, ∠ B

and

∠ C

is bisect at

O

.

We know that,

∠ B O C \;\; =90^{∘}+\;{∠ B A C}/{2}

\;\; =90+\;{50^{∘}}/{2}=90^{∘}+25^{∘}

∠ B O C \;\; =115^{∘}
