Answer:

Step-by-step explanation:

sides =8 cm, 17 cm and 15 cm

Area of triangle by Hero's Formula,

S=a+b+c/2

S=17+8+15/2

S=40/2

S=20

A= $\sqrt{s(s-a)(s-b)(s-c)}$

A= $\sqrt{20(20-17)(20-8)(20-15)}$

A= $\sqrt{(20)(3)(12)(5)}$

A= $\sqrt{3600}$

A=60 $cm^{2}$

Two cruise ships leave the same port with a 35° angle between their path. Cruise A is traveling at 18 miles per hour and Cruise

GuDViN [60]

Answer:

$20\:\mathrm{miles}$

Step-by-step explanation:

After travelling two hours, the two cruise ships form a triangle. One of the legs of this triangle will be the distance Cruise A travelled, and another will be the distance Cruise B travelled. We can find the distance they travel using:

$s=\frac{d}{t}, d=s\cdot t$

Cruise A is travelling at 18 miles per hour for 2 hours. Therefore, Cruise A has travelled:

$d=s\cdot t=18\cdot 2=36\:\mathrm{miles}$

Cruise B is travelling at 15 miles per hour for 2 hours. Therefore, Cruise B has travelled:

$d=s\cdot t=15\cdot 2=30\:\mathrm{miles}$

Because we are given the angle between these legs, we can use the Law of Cosines to find the third leg. The Law of Cosines is given by:

$c^2=a^2+b^2-2ab\cos C$ , where $a$ , $b$ , and $c$ are interchangeable. Let $c$ represent the distance between the two cruises. We have:

$c^2=36^2+30^2-2\cdot36\cdot30\cdot \cos 35^{\circ},\\c^2=426.63,\\c\approx \fbox{$20\:\mathrm{miles}$}$ (one significant figure).

Cole noticed that if he takes the opposite of his age and adds 40 he gets the number 28. how old is Cole?

AnnyKZ [126]

-x+40=28
-x=-12 (subtract 40 from both sides)

Divide by -1(in both sides)because you cant have a negative age.
COLE is 12

To check plug in the values.
