Answer: 1. 55 ft 2. 10 ft. 3.3 in.

Step-by-step explanation:

For question 9, you need to understand that the angle on the left is equal to the one on the right from the mirror priniciple. Now let's say the height of the dinosaur is x ft. We would get the equation 5.5/4 = x/40 and we get that x is 55, thus the height of the dinosaur is 55 ft

For question 10, we use the same similarity principle as we use in question 9 so given that the height of the light pole is h in. we get the equation

h/185 = 62/93

So, h is 123.33(I used a calculator, hope that's fine). Thus the height of the light pole would be 123.33 in. or 10 ft. 3.3 in.

Hope this helps!!!!
