Answer:
cos θ = 13/85, tan θ = 84/13, sec θ = 85/13, csc θ = 85/84
Step-by-step explanation:
θ in 1st quadrant, all the coordinates are positive
sin θ = 84/85 (for the right angle triangle ABC, A is the right angle and a the hypotenuse, b and c are legs. )
a = 85
b = 84
c = √85² - 84² = 13
-3/4 and 1/-2 is the correct answer.
9 dollars
Since 6 is 2/3 of the total price, and half of 6 is 3, add three to 6 and you get 9.
