Question

In a triangle $ABC$ if $\angle A={50}^o$ and $\angle B$ is obtuse angle then measure of $\angle C$ can be?

• A. ${91}^o$
• B. ${95}^o$
• C. ${60}^o$
• D. ${100}^o$

Answer 1

The correct option is C ${60}^o$

We know, every triangle should have at least two acute angle
Since, one angle given is acute (i.e., $\angle A={50}^o$) & other obtuse thus
Hence, third angle must be acute
$\therefore \angle C$ can be ${60}^o$
Answer is option C
