How to determine measures with trigonometric functions
In this problem we have two cases in which geometric diagrams and trigonometric functions are utilized to determine side lengths. Based on all informations presented in the images attached below, we proceed to find the side lengths:
Case A
h = (6 m) · sin 15°
h ≈ 1.553 m
Case B
Δh = 60 m /cos 36° - 60 m /cos 52°
Δh ≈ 310.309 m

What is the perimeter of the shape below, given a = 5.66, b = 13.75, c = 6.76, d = 4.59
Answers
Answer:
61.52
Step-by-step explanation:
5.66+ 13.75 + 6.76 + 4.59 + 5.66+ 6.76 + 13.75 +4.59
Answer:
61.52
Step-by-step explanation:
Given the values, you can solve for the remaining sides.
a + c will equal the side on the right and b + d will equal the side at the top.
So 2(a+c) + 2(b+d) will give the perimeter.
2(5.66+6.76) + 2(13.75+4.59) = 24.84 + 36.68 = 61.52

represents the total cost for a adult and c child tickets. Monica is purchasing tickets for
5 adults and 9 children.
Answers
Answer:
$210
Step-by-step explanation:
the expression is 25a+10c-5
where a=adults,c=children
and we have 5adults and 9 children
then 25a + 10c - 5 is
25(5)+10(9)-5
=125+90-5

Factorization of the given algebraic expression in its' simplest form is; B.–2(a + 6)
How to factorize an Algebraic Expression?To factorize an algebraic expression, it means that the highest common factors of the terms of the specific algebraic expression are determined and then we group the terms accordingly.
We are given the algebraic expression as;
6a – 4(2a + 3)
Multiplying the bracket out gives us;
6a - 4(2a) - 4(3)
= 6a - 8a - 12
= -2a - 12
Now, the highest common factor of the expression is 2 and so we have;
-2(a + 6)

Sandra has some nickels, dimes, and quarters which total $2.50. She has the same
number of nickels as quarters; however, she has twice the number of dimes as nickels.
How many of each type of coin does she have?
Answers
Answer:
5 nickels
10 dimes
5 quarters
Step-by-step explanation:
n = number of nickels
d = number of dimes
q = number of quarters
q = n
d = 2n
0.05n + 0.10d + 0.25q = 2.50
substitute
0.05n + 0.10(2n) + 0.25(n) = 2.50
0.05n + 0.20d + 0.25n = 2.50
0.50n = 2.50
n = 5
d = 10
q = 5
