Mathematics
1 answer:
ozzi3 years ago
6 0

Step-by-step explanation:

So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.

So we set up the equation

cos θ = adj/hype

cos θ = 5/8

θ = cos^{-1} (5/8)

θ=51.3178125...

θ=51°

Answer:

\frac{5}{12}

Step-by-step explanation:

The given problem is a subtraction problem between fractions. The first step in a problem like this is to convert both fractions to a common denominator. In other words, multiply both the numerator and denominator of a fraction by the same value such that the denominator of one of the fractions is the same as the other fraction. The numerator of a fraction is the value over the fraction bar, whereas the denominator is the value under it. Multiplying any fraction by a number over itself is the same as multiplying it by one, thus, the equation will remain true, and be equivalent to the original expression.

\frac{13}{12}-\frac{2}{3}

Convert to a common denominator,

\frac{13}{12}-(\frac{2}{3}*\frac{4}{4})

\frac{13}{12}-\frac{8}{12}

Now perform the subtraction, subtract one numerator from the other, remember, do no perfrom any more operations with the denominators,

\frac{5}{12}

Simplify the expression: –3(–7 + 3z)
aleksandrvk [35]

Hey there! I'm happy to help!

We want to multiply each term inside the parentheses by the number on the outside.

-3(-7)=21

-3(3z)=-9z

Therefore, our expression is 21-9z.

Now you know how to use the distributive property! Have a wonderful day! :D
