Tan(ANGLE) = Opposite Leg / Adjacent Leg
Tan(60) = Y/8
Y = 8 x tan(60)
Y = 8√3
Y = 13.9
Answer:
Step-by-step explanation:
If you're looking for what the half angle of the tangent of theta is, I'm a bit confused as to why you think the angle in the 4th quadrant, x, is relevant. But maybe you don't know it isn't and it's a "trick" to throw you off. Hmm...
Anyways, the half angle identity for tangent is

There are actually 3 identities for the tangent of a half angle, but this one works just as well as either of the others do, so I'm going with this one.
If theta is in QIII, the value of -4 goes along the x axis and the hypotenuse is 5. That makes the missing side, by Pythagorean's Theorem, -3. Filling in our formula:
which simplifies a bit to
and a bit more to

Bring up the lower fraction and flip it to divide to get
which of course simplifies to
-3. Choice A.
Answer:
363 feet
Step-by-step explanation:
330 ft / 10 seconds = 33 ft per second
33 * 11 seconds = 363 feet
3y+21+8y
11y+21 is the answer
Answer:
W=88
Step-by-step explanation:
4*(c-66)=c
4c-66*4=c
3c=66*4
c=22*4
c=88
w=88
