Answer:
The side opposite 30 is 9 ft.
The side opposite 60 is 15.59 ft.
Step-by-step explanation:
Below are pictures of how I got the answer.
I will provide steps to accompany each corresponding picture to further explain what I am doing.
1. This picture simply illustrates what the triangle looks like. The Hypotenuse is 18, as described in the problem.
2. I am showing how the sin will work. What is the opposite side and what is the hypotenuse. I picked this particular angle because it allow me to divide it by a number I already have, 18. I show that sin of 30 is 0.5
3. Now, we know what the side value is, 9. We can easily find the remaining side using Pythagorean theorem.
9^2 + y^2 =18^2
81 + y^2 = 324
y^2 = 243
y = 15.59
605,000 is scientific notation is
6.05*10000
=6.05*10^4
therefore the value of the exponent is equal to 4
