Question

Math help please

Answer 1

@dude will you help me

Answer 2

Ya

Do you know the trig ratio for cosine?

Answer 3

ajacent over hypotenuse

Answer 4

18/25

Answer 5

\(cos(\theta)=\frac{adjacent}{hypotenuse}\)

So theta is the angle measure

Answer 6

You're solving for the side, not the angle (we have that)

Answer 7

x/25

Answer 8

yeah, just add the angle

\(cos(18)=\frac{x}{25}\)

You want to isolate x, do you know how to do that here?

Answer 9

divide it by a number

Answer 10

D:

Answer 11

What is the opposite of dividing by 25?

Answer 12

multiply

Answer 13

Yeahhh

multiply 25 on both sides

Answer 14

cos(18)*25 then x/25*25?

Answer 15

Yeah

but 25 times 1/25 is just 1 so

\(25cos(18º)=x\)

Answer 16

23.77

Answer 17

Multiply them into your calculator (doing them by hand is impossible)

Make sure to have the mode on degrees if you're using a graphing or an online one

Answer 18

Yeah
