What is the measure of < b? a. cannot be determined b. 60° c. 25° d. 75°

Heya!

Here is your

The measure of all angles are 60°.

Here,

triangle ABC is an equilateral triangle (all sides are equal)

so, Its all angle measure same.

<A + <B + <C = 1800°

let <B = x

x+x+x =180°

3x = 180

x= 60°

Hence
<B = 60°

3.64 deaths an hour.

The answer is : 63explanation 60 times 0.05360+363
