Question

Find the area of each triangle.$b=4,c=10,A=70$

Short answer

The area of the triangle is$1.88squnit$

Step-by-step solution

Step 1.  Given information     

The given data is$b=4,c=10,A=70$

Step 2. Find the area of the triangle  

The area of the triangle is $k=\frac{1}{2}bc\sin A$

Here. $b=4,c=10,A=70$

localid="1647241017966" $$\begin{gathered} k=\frac{1}{2}bc\sin A \\ k=\frac{1}{2}\times 4\times 10\times \sin 70 \\ k=20\sin 70 \\ k=1.88squnit \end{gathered}$$
