- Im in class and I wonder how long my teachers chalk board is from the right side to the other while trying to plan out how my clasroom should look
- So I do the math if the hypotonuse is 15 and the angle is 37 and you use cos you do cos of 37 times 15 to find the width and get 12.0 feet long and that gets you the angle of the hypotonuse
- now i wonder if I put a desk by the white board and a painting on the white board if it will be similar to the others so lets do the math
- the desk measures a hypotonuse of 49 and an angle of 16 so if you do 49 sin 16 you get 13.5so the chalk board and the desk are not similar but hypothetically they could work since its 1.5 times larger
-
- the elevation of the triangle on the painting is 52 degrees the ajacent is 23 feet and we want to know the height so you do tan 52 times 23 and you get 29.4 feet tall
- In conclusion the painting is not similar to the other objects I want to put in my clasroom so I will need to get a diffrent painting a desks to make it similar in shape and sizes
