Answer:
Area of the triangle 5.9 sq. ft. .
Step-by-step explanation:
Length of two sides of the triangle are, 2.7 feet and 3.4 feet and the angle between them is 40° .
So, the area of the triangle is given by,
sq. ft.
<u>Answer:</u>
The area of triangle is
<u>Explanation:</u>
We are given two sides of a triangle and their including angle.
The two given sides of a triangle are , one is 2.7 ft and other is 3.4 ft
And the including angle is given to be 40°
The formula to find area of triangle when two sides and their including angle is given is-
=
where a and b are two sides and θ is the including angle.
Substituting the given values,
Area =
= 3.42
Hence is the area of triangle.
Since the ratio of the radius is 3 to 5 let's make them 3x and 5x(5x^2-3x^2)pi=322x^2*pi=322x^2=10.18.....didnt round yetx^2=5.0929...Now 5x^2*pi=80
175 / 5215 ≈ 0.0336 = 3.36%
3(3x+7)
9x+21=3(3x+7)
