Question

find area of |\ ABC given that ABC=CAB=45, AC= 8 cm​

Answer 1

Answer

32

Step-by-step explanation

Given : b=8 , ∠A=45°=∠B

By the Sine Rule,

$\frac{a}{sin A}$=$\frac{b}{sinB}$

Therefore, a=b=8

Now since ∠C=90°, therefore  AB=c=8$\sqrt{2}$

Therefore area of ABC=$\frac{1}{2}$(8)(8)=4(8)=32 sq. units
