Using the law of cosine:
Cosine(angle) = Adjacent leg / Hypotenuse
You are given the angle, and the adjacent leg and need to solve for X, which is the hypotenuse.
Using the formula above you have:
Cosine(58) = 17 / x
Solve for x by dividing 17 by cos(58)
x = 17 / cos(58)
x = 32.08
The expression is (15+6) */* 3. This is because we add up all the costs to get the total, and divide the total by three because there are three friends splitting the cost.
Tenth place is the first place after the decimal which is 4.999
^
The answer is 4.9
5/21 is a repeating decimal but the first digits are 0.238095
Answer:
because when the value of x is replaced in the factorisation it Will be equivalent to 100
