Answer:
The length of BC is needed because it is the side opposite ∠A.
Step-by-step explanation:
Given the right angles triangle as shown in the attachment, we can get sin(A) without using Pythagoras theorem. Instead we will use SOH CAH TOA trigonometry identity.
According to SOH:
Sin(A) = Opposite/Hypotenuse
Sin(A) = |BC|/|AB|
Opposite side of the triangle is the side facing ∠A.
Based on the formula, we will need to get the opposite side of the triangle which is length BC for us to be able to determine sinA since the hypotenuse is given.
Answer:
commutative property of multiplication
Step-by-step explanation:
The commutative property of multiplication is correct. The commutative property of multiplication is basically arranging the numbers in any way and it won't change the product.
The associative property of multiplication is arranging the numbers in parenthesis and it won't change the product either.
Heyy it’s 1:50! you would put the original two numbers in a ratio 16:800 divide by 8 and get 2:100 then divide by 2 and get 1:50!
Answer:
Each will pay $61.75.
Step-by-step explanation:
How many gallons were used?
Each 100 miles, 3 + 1/4 = 3 + 0.25 = 3.25 gallons are used. The trip has 1500 miles.
100 miles - 3.25 gallons
1500 miles - x gallons
Cost
Each gallons costs $3.80.
48.75 gallons cost 48.75*3.80 = $185.25
Split among the three friends envenly, how much will each pay?
185.25/3 = 61.75
Each will pay $61.75.
