Mistresso uses the formula for the area of a non right angle triangle to find the area of each triangle which the victims are held in. She then divides this by 2, since every person takes up 2² units of space. The captain continues to solve the question by multiplying the answer by 5, since there are 5 triangles which the victims are held in. She finds that there are 210 people who have been captured and put into the devils pentagon. Off she goes to rescue them!
angle C= 45.6 degrees
area of triangle: 1/2absinCA=1/2 x 13 x 13 x Sin(45.6)A=84.4m²Each person takes 2² units of space. no. of people per triangle=84.4/2no. of people/triangle=42there are 5 triangles, with victims inside.5 x 42=210
Captain Mistresso enjoys the rest of her day by saving the 210 people from the devils dungeon, and making sure the villain does not ever do such a horrible act again. She is praised by everyone once again.
AH GUYS! IT'S MY PLEASURE SAVING YOUR LIVES!
YOU'RE THE BEST
I LOVE YOU CAPTAIN
YOU'RE MY HERO!
You do not need to cancel out the entire sound wave. You just need to cancel out half of it. You've got to hurry before the sound waves reach every corner of the world. GOOD LUCK. THE PEOPLE ARE DEPENDING ON YOU!
Captain Mistresso wake up!There is a new problem! We have just been notified that there is an evil man using a dangerous weapon. He is producing sound waves, too loud for humans, just outside of town. You've got to stop it
We know that the machine he is using, has an option of entering equations to produce different levels of sound waves. Our villain has entered an equation of 48sin(x).
Captain Mistresso has woken up and has read the upsetting news. She knows what he job is and gets to work right away!
OH NO!I HAVE TO SAVE THE PEOPLE RIGHT AWAY
Captain Mistresso uses trigonometric functions to figure out how to cancel out the soundwaves halfway. She knows that the soundwaves have an equation of 48sin(x)
