Question

Look at the figure on the side. Considering r = 1 and a = √√3,
calculate the angles a, ẞ and the measure of side b.

Answer 1

Answer:

Step-by-step explanation:

r = 1 so BC = 2.

The triangle is a right triangle with <BAC = 90 degrees.

So,  By Pythagoras

2^2 = b^2 + (sqrt3)^2

b^2 = 4 - 3 = 1

So b = 1

tan a = sqrt3

So < a = 60 degrees

and ẞ =  90 - 60

          = 30 degrees.
