How would you calculate the angle? Do we use sin? cos? tan?

hamidiso23:

think so

AZ:

no, which one do we use?

AZ:

We have an angle we have the side opposite it and we have the side adjacent to it

hamidiso23:

doesnt say which to use ig any

AZ:

no LOL you have to figure out which one to use

hamidiso23:

i d k

AZ:

if you have the OPPOSITE side and the ADJACENT side do you use sin = opposite / hypotenuse or do you use cos = adjacent/ hypotenuse or do you use tan = opposite/ adjacent

AZ:

which one of those has BOTH opposite and adjacent???

hamidiso23:

tan

AZ:

yes so that means \( \tan \theta = \sf \dfrac{opposite}{adjacent}\)

hamidiso23:

yh

AZ:

so your opposite side is 15 your adjacent side is 10 so \(\tan \theta = \dfrac{15}{10}\)

hamidiso23:

1.5

AZ:

yes now use the arctan or tan^-1 to calculate the angle

AZ:

so basically \(\theta = arctan(1.5)\) \(\theta = ?\)

AZ:

and remember to be in degrees not radians if you want your answer in degrees

hamidiso23:

my bad

hamidiso23:

i had like 15 dms lol

hamidiso23:

1.5 times what?

AZ:

...

hamidiso23:

0=1.5 u said

snowflake0531:

No Put into your calculator, or google arctan(1.5)

hamidiso23:

0.982793723 rad

snowflake0531:

DEGREES

hamidiso23:

56.3099325 degrees

snowflake0531:

round

AZ:

That's your answer

hamidiso23:

56.3?

AZ:

yeah

hamidiso23:

or just 56?

AZ:

whatever your question wants, mate

snowflake0531:

SInce there's a 0 after the 3, just do 56.3

hamidiso23:

but its a greaph

hamidiso23:

greaph

snowflake0531:

whatever, just whatever it wants

hamidiso23:

graph

AZ:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @hamidiso23 or just 56? \(\color{#0cbb34}{\text{End of Quote}}\) although if it's the same instructions as the previous one, just stick with 56

hamidiso23:

ight

hamidiso23:

on a graph

hamidiso23:

can u put 56.3

AZ:

what do you think?

hamidiso23:

I think u cant

AZ:

good

hamidiso23:

so just 56

AZ:

yes

hamidiso23:

tnx
