Find the Value of P rounded to the nearest tenth

a.) 26.3
b.)32.5
c.) 46.1
d.) 51.9

Answer 1

71 is degrees

Answer 2

What class is this for?

Answer 3

Geometry

Answer 4

Do you know sine and cosine?

Answer 5

Yes

Answer 6

I got 43.5... but I'm doing something wrong

Answer 7

is that a right angle?

Answer 8

Yes

Answer 9

on no P is the hypotenuse right?

Answer 10

then cosine is "adjacent over hypotenuse" so \[\cos(71^\circ)=\frac{15}{P}\] solve for \(P\)

Answer 11

So divide 17 and 15?

Answer 12

that makes \[P=\frac{15}{\cos(71^\circ)}\]

Answer 13

i don't see a 17 in the picture

Answer 14

lol sorry I meant 71

Answer 15

but I divide those?

Answer 16

i wrote the answer above

Answer 17

I don't see it

Answer 18

\[\cos(71^\circ)=\frac{15}{P}\\
P=\frac{15}{\cos(71^\circ)}\]

Answer 19
