# Thread: find exact values for theta

1. ## find exact values for theta

what does the theta sign and red arrow symbolize?

the question:

my work:

i don't know if this is correct. as you can see, i used the pythgorean thm to find the hypotenuse (5). then using SOHCAHTOA, i found the answers? correct or do they have to be in decimal form since it says exact values?

2. Your answers are correct. Fractions are exact values and do not need to be turned into decimals.

note: the last can be rewritten as

$\tan(\theta)=-\frac{4}{3}$

3. gee, thx pal. no kidding, you're the best.
