Find the area of △ABC with side lengths b = 6 and c = 17, and included angle A = 135∘. Round your answer to the nearest tenth

Cloud [144]

Answer:

Area = 36.1 sq. units

Step-by-step explanation:

We will use the "included angle area" formula for a triangle to solve this problem.

The formula is:

$A=\frac{1}{2}abSinC$

Where

a and b are the two sides given

C is the angle given BETWEEN the two sides

From the problem, we can write:

the two sides are 6 & 17, so that will be "a" and "b" of the formula

the included angle is 135, so that will be "C" of the formula

Substituting, we find the answer:

$A=\frac{1}{2}abSinC\\A=\frac{1}{2}(6)(17)Sin(135)\\A=36.06$

Rounded to 1 decimal place,

Area = 36.1 sq. units

A football field measures 300 feet in length. It can also be expressed as approximately

Mariana [72]

Answer: n=-2

Step-by-step explanation:

Given

The length of the football field is $300\ ft$

In the mile, it can be expressed as $5.7\times 10^n\ mile$

Also, $5280\ ft=1\ mile$ or

$1\ ft=\dfrac{1}{5280}\ miles\\\\1\ ft=1.893\times 10^{-4}\ miles$

converting $300\ ft$ to miles

$\Rightarrow 300\times 1.893\times 10^{-4}\\\Rightarrow 5.68\times 10^{-2}\approx 5.7\times 10^{-2}$

Comparing it with the given value $5.7\times 10^n\ mile$

we get $n=-2$
