∠a is an acute angle in a right triangle. given that cos a=12/13, what is the ratio for sin a? enter your answer in the boxes as a fraction in simplest form

sin A =

Step-by-step explanation:

As per the statement:

∠A is an acute angle in a right triangle.

Given that:

We have to find Sin A:

Using the formula:

Substitute the given values we have;

⇒

⇒

Therefore, the value of sin A as a fraction in simplest form is,

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
