A slide 4.4 m long makes an angle of 33 with the ground. How high is the top of the slide above the ground
svp [43]
Using the information given we will only need the Cosine and Sine equations.  i made a diagram (cant take a picture, in my study hall) labeled the sides of the triangle A, B, and C.  with C as the hypotenuse, A as the Opposite, and B as the adjacent (will not be needed as A is the height). i will be rounding the th nearest thousandth. 
Using Sine (SIN=Opposite/Hypotenuse), we can find A.

SIN(33)=A/4.4

SIN(33)≈.545

.545≈A/4.4

now multiply each side by 4.4 to get rid of the division

(.545*4.4)≈((A/4.4)4.4)

2.396≈A
 

so the answer would be that the slide is about 2.396 M high

scale factor = \frac{14}{5}

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, image to original.

scale factor = \frac{7}{2.5} = \frac{7(2)}{2.5(2)} = \frac{14}{5}

If the car were 6 feet tall, the model would be 1in tall. so if the model is .75in then you would do 75% of 6, so therefore, you will get 4.5.
