2 hikers set out from the same campsite. One walks 7km in the direction of 043°T and the other walks 10km in the direction 133°T. What is the bearing of the first hiker from the second? I...
For the kite shown in the figure, use the Law of Cosines to find the lengths of the two dowels required for the diagonal supports, where a = 70 cm, b = 150 cm, α = 55°, and β = 42.24°.
trig need help with me. please!!
Consider the equation cos(4.38t)=0.1 Find the smallest positive solution in radians and round your answer to 4 decimal places
Find the exact value of each expression:\\ (a) sin-1(√(3)/2) = (b) cos-1(-1) =
Use the sum of difference formula to find the exact value
Help simplify the expression and show the steps too!
in triangle ABC a=3 b=5 and cos(C)= 13 what is the value of c
Show that 2 tan20° + 4 tan40° + 8 tan 80° = 9(cot10° - tan10°). Thank you :)
Given that cotθ=k and that θ is acute, express tan3θ in terms of k. Ans: (3k2-1)/(k)(k2-3) Thank you :)
(i) Given that cos A =3/5 and cos(A+B) =-5/13, where A and B are acute, evaluate sin B. (ii) Another acute angle C is such that sin C=12/13. Find sin(A+B+C). (iii)...
