Question

Find the area of the triangle ABC given angle A = 45°, b = 8, and c = √2. 4 4√2 8 8√2

Answer 1

Answer:

Area  = 4 units²

Step-by-step explanation:

We have given that

Angle A  = 45° , b = 8 and c = √2

We have to calculate the area of the triangle.

The formula to calculate the area is :

A  =  1/2×b×c×sin(A)

Putting values in above formula, we have

A  =  1/2×8×√2 × sin(45)

A  =  1/2×8×√2×1/√2

A  = 4 units² which is the answer.
