Find the area of the triangle ABC given angle A = 45°, b = 8, and c = √2?
Solution:
A = 45°, b = 8, and c = √2 [Given]
The formula to find the area of the triangle is
A = ½ × b × c × sin A
Substituting the given values
A = ½ × 8 × √2 × sin 45°
By further calculation
A = ½ × 8 × √2 × 1/√2
So we get
A = 4 unit2
Therefore, the area of the triangle is 4 unit2.
Find the area of the triangle ABC given angle A = 45°, b = 8, and c = √2?
Summary:
The area of the triangle ABC given angle A = 45°, b = 8, and c = √2 is 4 unit2.
