Answer:
Step-by-step explanation:
Given:
[∵ 
]
Squaring both sides.
[∵ ![cot^2\theta =csc^2\theta-1]](https://tex.z-dn.net/?f=cot%5E2%5Ctheta%20%3Dcsc%5E2%5Ctheta-1%5D)
]
Adding 1 to both sides.
[Taking LCD=9 and adding fractions ]
Taking square root both sides.
∴
1. Find the "opposite side," if the angle is 60 degrees and the hyp is 6:
opp opp sqrt(3)
sin 60 deg = ------- = -------- = ----------
hyp 6 2
Cross-multiplying, 2(opp) = 6sqrt(3), so that opp = 3 sqrt(3) (answer)
2. Use the Pyth. Thm. to find the "adjacent side:"
[3sqrt(3)]^2 + x^2 = 6^2, or 9(3) + x^2 = 36, or x^2 = 9, or x = 3.
The lengths of the legs of this 30-60-90 triangle are 3 and 3 sqrt(3).
check: Does 3^2 + [3sqrt(3)]^2 = 6^2?
Does 9 + 9(3) = 6^2? YES
Angle GQK=90
GQK=GQL+LQK
90=3n+(4n-15)
n=15
Therefore angle LQK=4(15)-15
=45
