The answer (if I did it right) is 490. you would do what is in the parentheses first and then subtract the two.
First we imagine triangle. Triangle vertices are: xy coordinate center, point (4,3) and projection of that point on x axis (x = 4). Because angle is in standard position, just from knowing (4,3) coordinates we know 2 of triangle sides and we can find its hypotenuse which will be marked as "h":
Now the sinq is:
sinq = 3/5 because of definition of sin.
sin = opposite side of triangle/hypotenuse.
answer is 3/5
Answer:
12.5 in²
Step-by-step explanation:
Given:
Height of tile = 2.5 in
Base of tile = 2*height of tile = 2*2.5 = 5 in
Length of other side of tile = 2.5 in
Required:
Area of the tile
SOLUTION:
Area of the tile = area of parallelogram
All we need to calculate the area of the tile, is the base and the height.
Area of parallelogram = base × height
Area of tile = 5 × 2.5 = 12.5 in²
Answer:
sec or 1/cos
Step-by-step explanation:
1/sin * sin/cos
sin cancels out
1/cos = sec
Fractions are one number over another number
