Please help me I’m stuck.

Answer:

Step-by-step explanation:

We will use the general area formula for finding the area of triangle when you are given information for SAS, which we have been.

A=\frac{1}{2}absinC , where a and b are the given side lengths and C is the included angle. You can ONLY use this when you have the info for SAS in a triangle. For us,

a = 17, b = 15 and C = 35 degrees.  Filling in:

A=\frac{1}{2}(17)(15)sin35

Do that on your calculator in degree mode and you'll find the area to be

73.1 meters squared

Answer:

A. 11\frac{5}{8}\textrm{ inches}

Step-by-step explanation:

Given:

The regular polygon is a decagon having 10 sides.

Perimeter of the given polygon is,

P=116\frac{1}{4}\textrm{ inches}=116.25\textrm{ inches}.

We know that, perimeter of a regular polygon of n sides is given as,

P=na where, a is the length of each side.

Here, n=10,P=116\frac{1}{4}\textrm{ in}

Plug in these values and solve for a. This gives,

P=na\\116\frac{1}{4}=10a\\116.25=10a\\a=\frac{116.25}{10}=11.625=11+\frac{625}{1000}=11+\frac{5}{8}=11\frac{5}{8}\textrm{ in}

Therefore, the side length of the given polygon is 11\frac{5}{8}\textrm{ inches}
