Need with math question its about finding area of a triangle i would be really grateful is someone me with a few questions after this

65.8 in²

Step-by-step explanation:

Given a triangle with 2 sides and the included angle then the area (A) is

A = 0.5 × a × b × sinΘ

where a, b are the 2 sides and Θ the included angle

here a = 18, b = 12 and Θ = 147°, hence

A = 0. 5 × 18 × 12 × sin147°

   = 108 × sin147° ≈ 65.8 ( to the nearest tenth )

The area of triangle is 59.2 in².

Step-by-step explanation:

If a, b and c are three sides of a triangle then the area of triangle by heron's formula is

         .... (1)

where,

From the given figure it is clear that the length of sides are 12 in, 18 in and 28.8 in. The value of s is

Substitute s=29.4, a=12, b=18 and c=28.8 in equation (1).

Therefore the area of triangle is 59.2 in².

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
