Important relationships to note:

sec(x) = 1/cos(x)
cot(x) = 1/tan(x)
cosec(x) = 1/sin(x)

Thus, we can say:
sec(x) · tan(x) · sin(x) = [sin(x) · tan(x)]/cos(x)
= tan(x) tan(x)
= tan^2(x)

Lita,Kala, and Rose entered a typing competition. Lita typed 2 times as fast as Kala. The ratio of the number of words Kala type

Jobisdone [24]

If the ratio from Kala to Rose is 4:1, then for the 48 words Rose typed Kala typed 192 words. 48*4=192
Then Lita types twice as fast so 192*2=384.
It should be 384 words.

With a tailwind, a aircraft can fly 360 miles in 3 hrs. Against this same wind, the aircraft can fly the same distance in 4hrs.

Leona [35]

Answer:

15mph

Step-by-step explanation:

360 divide by 3 = 120

360 divide by 4 = 90

120 - 90 = 30

30 divide by 2 (cause boosting speed and drag) = 15

so let's check

120-15=105

105+15=120

105-15= 90

so the answer's 15.

Does anyone know how to solve this?

horsena [70]

Answer:

$x=360$

Step-by-step explanation:

The inscribed angles theorem states that when given a circle, with an angle that has its vertex at the center of the circle, the measure of the angle is congruent to the measure of the arc surrounding it. One can apply this knowledge here by stating the following,

$m$

Substitute,

$x=2\pi$

However, this answer is in radians, it is the literal measurement. One must convert into degrees so that the answer fits the format of the question. The conversion rate to switch between radians and degrees is the following,

$degree=\frac{\pi}{180}radians$

Substitute,

$degree=\frac{180}{\pi}(x)\\\\degree=\frac{180}{\pi}(2\pi)\\$

Simplify,

$degree=\frac{180*(2\pi)}{\pi}\\degree=360$
