Question

Find the area of the triangle with 4 = 42º. b = 3 feet, and c= 5 feet. Round to the nearest tenth.​

Answer 1

Answer:

Area = 5 sq ft

Step-by-step explanation:

Area of a Triangle with Side angle side method is given by the formula given as under

$\ Area=\frac{bc \sin A}{2}$

In our problem we are given that

$A= 42$◦

$\sin 42=0.6691$

$b=3 \ feet$

$c=5 \ feet$

Putting these values in the formula we get

$\ Area=\frac{3 \times 5 \sin 42}{2}$

$\ Area=\frac{15 \times 0.6691}{2}$

$\Area=5.01$

Hence Area of the Triangle is 5 Sq Ft
