Answer:
1) 
2) 





Step-by-step explanation:
The Pythagorean Theorem is:

Where a is the hypotenuse and b and c are the legs.
The missing side lenght is one of the legs, then you must solve for one of them. Therefore, this is:

MEASURE OF ANGLE:
Keep the identities on mind:



Susbstitute values, then:






Step-by-step explanation:
The number 7273 is called the numerator or dividend, and the number 6 is called the denominator or divisor.
The quotient of 7273 and 6, the ratio of 7273 and 6, as well as the fraction of 7273 and 6 all mean (almost) the same:
7273 divided by 6, often written as 7273/6.
Read on to find the result of 7273 divided by 6 in decimal notation, along with its properties.
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

Given Points are (-3 , 5) and (6 , -1)
here x₁ = -3 and x₂ = 6 and y₁ = 5 and y₂ = -1

Option D is the Answer
Part B. f(x) = 90 + 0.11x
f(300) = 90 + 0.11(300) = 90 + 33 = $123
f(300) represents the total cost, in dollars, for renting a car for a week and driving it for 300 miles.
The answer would be 4 cause .5 is half of 1 and 4 is half of 8.
