Step-by-step explanation:

Remember to follow the rule: SohCahToa:

Sin (S) = Opposite/Hypotenuse

Cos (C) = Adjacent/Hypotenuse

Tan (T) = Opposite/Adjacent.

Hypotenuse is always the longest side. Adjacent is the side next to the angle, Opposite is the side opposite of the angle.

Sin(A) = (Opposite/Hypotenuse) = 8/17

Tan(A) = (Opposite/Adjacent) = 8/15

Cos(A) = (Adjacent/Hypotenuse) = 15/17

Sin(B) = (Opposite/Hypotenuse) = 15/17

Tan (B) = (Opposite/Adjacent) = 15/8

Cos (B) = (Adjacent/Hypotenuse) = 8/17

Anna buys 12 pens and 20 pencils for a total cost of $16. One pen costs $0.40 more than a pencil. What would one pencil and one

vladimir2022 [97]

It is given in the question that

Anna buys 12 pens and 20 pencils for a total cost of $16. One pen costs $0.40 more than a pencil.

Let the cost of pencil is $ x .

Therefore cost of pen is

$$(x+0.40)$

According to the question

$12(x+0.40)+20x =16$

Distributing 12 and combining like terms, we will get

$12x+4.8+20x=16\\32x = 11.2\\x = 0.35$

Therefore cost of pencil is $0.35 and cost of pen is

$0.35+0.40=0.75$
