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

A = 63.1 ft²

Explanation:

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

Answer 2

31.6 square feet

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 =
`(1)/(2)bc sin A`

`(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.
