Trigonometric ratio</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let b represent the base of the triangle and h the height, hence:
sin(60) = h / 18
h = 15.6 feet
sin(30) = b / 18
b = 9 feet
The area of triangle = (1/2) * b * h = 0.5 * 9 * 15.6 = 70.1 ft²
70.1 ft² of fabric is needed by Lacy to make the sail boat.

I am assuming that you are supposed to answer this division problem through the long division method. So my answer is going to be a step-by-step description of the long division solution for this problem.
The first step is to move the decimal point of the dividend and the divisor. Hence, 1264.0 and 17. The decimal point of the quotient shall then be written in alignment with the decimal point of the dividend.
Then we proceed with the division process, 126/17 gives us 7 (write this above the division bar). 7 multiplied by 17 gives 119 (write this under the divisor). So 126-119 is equal to 7. We then bring down the digit after 126 of the divisor, which is 4. So we now have 74. 74 divided by 17, we get 4. 4 multiplied by 17 gives 68. We subtract 68 from 74 and we have 6, bring down 0, we have 60. We then repeat the division-multiplication-subtraction process until we get to the third decimal place of the quotient.
Finally, the answer is 74.352.
Step-by-step explanation:
given f(x) = 2/x and g(x) = 2/x
f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x
g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x
therefore they are inverses
since f(g(x)) = g(f(x)) = x.
