The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).
Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse
Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse
Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.
The acronym to remember this is SOHCAHTOA
SOH | CAH | TOA
SOH means sin(x) = opposite/hypotenuse
CAH means cos(x) = adjacent/hypotenuse
TOA means tan(x)= opposite/adjacent
cosB = length of adjacent side/length of hypotenuse = 7/25
tanB = length of opposite/length of adjacent = 24/7
sinB = length of opposite/length of hypotenuse = 24/25
Answer:
Tasha ordered 9 ounces of salad
Step-by-step explanation:
<u><em>The complete question is</em></u>
Tasha ordered soup and salad for lunch. The soup cost 15 cents per ounce, and the salad cost 20 cents per ounce. If Tasha ordered 10 ounces of soup for lunch and the total cost was $3.30, how many ounces of salad did
Tasha order?
Let
x -----> the ounces of soup ordered
y -----> the ounces of salad ordered
we know that
The ounces of soup ordered multiplied by their cost plus the ounces of salad ordered multiplied by their cost must be equal to $3.30
so
-----> equation A
substitute the value of x in the equation A and solve for y
Subtract 1.50 both sides
Divide by 0.20 both sides
therefore
Tasha ordered 9 ounces of salad
Step-by-step explanation:
From the given table it is obvious that 162 is the largest number of the given numbers which corresponds to 45° angle.
So, he should kick the football at 45° angle for maximum distance.
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.
<span>ABCDE~QRSTU</span>
Three times = 3 ×
<span>The difference of 65 and 48 = 65 - 48 = 17
(Difference = subtract)
That equals 3 </span>× 17
<span>
Answer = 3 </span>× 17
<span>(3 </span>× 17 = 51)<span>
Hope this helped☺☺
