Question

Find the area of the following figure.
Formula:
Area of triangle ABC= 1/2 ab sin A = 1/2 bc sin A = 1/2 ac sin B​

Answer 1

Answer:

∆ be the area of a triangle ABC, Proved that, ∆ = ½ bc sin A = ½ ca sin B = ½ ab sin C

That is,

(i) ∆ = ½ bc sin A

(ii) ∆ = ½ ca sin B

(iii) ∆ = ½ ab sin C
