Ms. Araya wants to figure out the angle of inclination is, but we only know the Adjective and Hypotenuse. For this, we will the Cosine, which will be Cos -1 45/90 to find that the angle of inclination is 60 degrees.

At what angle can we have a perfect view of the high temple?
We know that we are 90 ft away from the temple and 180 ft high. We will use the Sine, which we will have Sin-1 90/180 to find the perfect view which is 30 degrees

We want to know the angle of elevation of this historic tower. With the given of the opposite is 40 and the hypotenuse is 100. We will use Sin -1 which will be Sin-1 (40/100) is 24 degrees.

Mr. Felix is assigned to know the higth of the pyramid for his homework. He knows that his distance from the pyramid is 9 ft. and the angle of inclination is 50 degrees. Now he will use the tan formula which is tan 50(9) and now he got 450 ft!

Ms. Araya was walking through her friends house. and all of the sudden she heard "meow". She looked up and saw cat stuck in the tree. sally needed to figure out how high the cat was. So, she used a trig function! Ms. Araya is looking at the cat from a 57 degree angle and is standing 5 feet away from the tree.. tan(57)*5=7.6 the cat is almost 8 feet high!
We needed to know how they could put the stick back onto the house. the angle of 35 degrees. Where the stick lays is 7 feet long. How long is their stick? sin35(7/x) = 12.4 feet. The stick is about 12 feet long.
