Question

sec 45 degrees=?

Answer 1

one over the cosine of 45 degrees

Answer 2

\[\sec(x) = \frac{1}{\cos(x)}\]

Answer 3

\(\large\color{slate}{ \sec(45^\circ)=s\sqrt{2}/s=? }\)

Answer 4

do you know what
\[\cos(45^\circ)\] is ?

Answer 5

guess that is a better start sate...

Answer 6

Okay i am bad at maaking the little degree symbol -.-

Answer 7

\circ

Answer 8

\[x^\circ\]

Answer 9

\[\cos(45^\circ) =\frac{1}{\cos(45^\circ)}\]

Answer 10

there we go.

Answer 11

nice

Answer 12

cos 45=1/1\[\sqrt{2}\] on a 45 45 90 triangle

Answer 13

i menat 1/1 square root of 2

Answer 14

i think that was supposed to be \(\frac{1}{\sqrt2}\) right?

Answer 15

yeah

Answer 16

flip it

Answer 17

square root of 2

Answer 18

yup

Answer 19

\[\cos(45^\circ) =\frac{1}{\cos(45^\circ)} = \frac{1}{\dfrac{\sqrt{2}}{2}} = \frac{2}{\sqrt{2}}=\sqrt{2}\]

Answer 20

Good job.

Answer 21

thank you so much! and this will apply to a 45 45 90 triangle right?
