Question

Find the area of the triangle with A=35 degrees, b=11 feet and c=10 feet . Round to the nearest tenth

Answer 1

Answer:

A = 63.1 ft²

Step-by-step explanation:

Area of triangle = the product of two sides * sin the angle included between them

Answer 2

Answer:

31.6 square feet

Step-by-step explanation:

DEFINITION

In a triangle, an Included Angle is the Angle between two adjacent sides.

Given a triangle with two sides and an included angle,

The Area of a Triangle =$\frac{1}{2}bc sin A$

$\frac{1}{2}*11*10* sin 35 =11*5* sin 35=31.55 ft^2$

The area of the triangle is 31.6 square feet to the nearest tenth.
