Question 584202: is it possible to construct a triangle with side lengths 10,11, and 20
Click here to see answer by nerdybill(7384)

Question 584372: Hello, I'm working on the following for MATH 421A(Acedemic Grade 10). I'm on unit 5 Trigonometric Ratios. I can understand a bit like how Trig' Ratios : of any acute angle, Finding size degree of each angle, Finding side lengths in any right angle and Finding angles in any right triangle. I dont know if i am looking at it wrong or just too long or what. But i have been on the same question now since last night and i think i need some help on it. I think i'm understanding the formulas a little bit. Question states : "Solve each triangle. Round each side length to the nearest unit and each angle to the nearest degree."
c=56, 33 degrees
This is how i did it :
"Nearest unit": X =33 degrees "THEN" 56 SIN 33 = 30.4 -> Answer1: 30cm
--
56
"Nearest degree": SIN-1 (33 / 56)= 36.1degrees "THEN" 90+36.1=126.1 "THEN"
180-126.1= 53.9 -> Answer2: 54 degrees
"Nearest unit again": SIN 54 degrees = 33 opp-->TAN 33 -> 23.9 ->Answer3: 24cm
-- --- --
B ajd 56

So i got every single question wrong in the back of the book.
These are the CORRECT ANSWERS:
Answer1: b=30cm Answer2:Right angle A = 57 degrees Answer3: a=47cam
Answer 1:Has a sign in the book i cant type, it is a right angle pointing to the right with a A beside it.
Answer 2 & 3: Have both lower case letters a & b and then = a unit (This case it's CM).
So i got them totally wrong, hopefully you can understand what i am trying to say and come up with a answer for me. If not, don't worry about it. I will just ask my teacher on Monday. But it would be really lovely if you could get back to me tonight or tomorrow!
Thank you very much.

Question 584743: I need help solving this problem: You have climbed to the top of a tall tree. When you get to the top, you use your clinometer to discover that the angle between the tree and the line of sight to your red lunchbox is 30o. You know you left the lunchbox 20 meters from the base of the tree. How tall is the tree?
I have seen another answer for this question on here, but it wasnt solve fully so i couldnt finish solving it. This was it: 20/x = tan(30) then you solve for x 20/tan(30) = 20 (sqrt)3 = 34.64 HELP ME!! please?
