What are trigonometric functions?

There are six major trigonometric functions as -

• Sine(x)

• Cosine(x)

• Tangent(x)

• Cotangent(x)

• Secant(x)

• Cosecant(x)

We can write the relation between them as -

• Sine = 1/cosecant

• Cosine = 1/secant

• Tangent = 1/Cotangent

Given is a right angled triangle as shown in the image attached.

We can find the unknown values using the trigonometric functions. We know that the sine function is the ratio of perpendicular and hypotenuse. So, we can write -

sin(54) = x/15

{x} = 15 sin(54)

{x} = 15 x 0.80

{x] = 12

Therefore, the measure of the unknown length is equal to 12.

A bike rental costs $8 per hour. Desiree has a coupon for 2 free hours. To find how many hours she can rent with $40, Desiree sets up the equation 8(x – 2) = 40, where x is the number of hours.Drag equations into order show a way to solve for x

8x = 56
8x + 16 = 40
x = 3
8x = 24
x = 7
8x – 16 = 40
8(x – 2) = 40

in a club of 35 boys and 28 girls,80% of the boys and 25% of the girls have been member for more than 2 years.if n percent of the club have been member for more than 2 years,what is the value of n?

Answers

find them
80%=80/100=8/10=4/5
25%=25/100=1/4

4/5 of 35 +1/4 of 28=

35 have been

find 35 out of all
all=boys+girls=35+28=63
