Answer:

The sin of 45 degrees is radical(2)/2 The cos of 45 degrees is radical(2)/2 Using the identities for the tangent function, tan(x) = sin(x)/cos(x) We show sin(45)/cos(45) = [radical(2)/2] / [radical(2)/(2)] = 1 *NOTE* Any non-zero number divided by itself is equal to one.

Question:

A triangle has an angle ratio of 3:5:4. What is the measurement of each angle in the triangle?

Answer:

For this question, one must realize that every triangle has an area of 180 degrees. Thus the ratio 3:5:4 can be expressed as an addition equation with "x" as our unknown variable 3x + 5x + 4x = 180 12x = 180 x = 15 Now we take our ratio to figure out each side: 3x = 3*15 = 45 degrees 5x = 5*15 = 75 degrees 4x = 4*15 = 60 degrees

Question:

Jonny wanted to purchase some food from a restaurant. A slice of pizza costs $2, the cheeseburger costs twice as much as the pizza, the fries cost $2.50 less than the cheeseburger, and icecream costs half the price of the fries. How much money would Jonny have to pay if he bought all of these food items?

Answer:

To answer this question, we need to figure out how much each item costs: Pizza = $2 Cheeseburger: 2*$2= $4 Fries: $4 - $2.50 = $1.50 Ice Cream: $1.50/2 = $0.75 The Total Cost is Pizza + Cheeseburger + Fries + Ice Cream which is $2 + $4 + $1.50 + $0.75 = $8.25 Jonny would need to pay $8.25 to buy his food items
