If sin θ = 1 over 4 and tan θ > 0, what is the value of cos θ? (1 point)
Dima020 [189]

Answer:

There are two options: b) \frac{\sqrt{15}}{4}, c) \sqrt{15}.

Step-by-step explanation:

By Trigonometry, we know that function tangent is equal to the following identity in terms of functions sine and cosine:

\tan \theta = \frac{\sin \theta}{\cos \theta} (1)

If we know that \tan \theta > 0 and \sin \theta = \frac{1}{4}, then \cos \theta > 0. Hence, we have two possibilities: b) \frac{\sqrt{15}}{4}, c) \sqrt{15}.

What is the length of BC¯¯¯¯¯ ?
balandron [24]

Answer:

The length of BC is 17

Step-by-step explanation:

When we construct a triangle with the data, we will end up a  isosceles triangle.

In a isosceles triangle , we know that tow angles and two sides are equal

The questions states that

\angle b = \angle c

Then sides  AC  and AB  are also equal

On equation their values

2X - 8 =  X+9

2X = X + 9 +8

2X = X + 17

2X - X = 17

X =  17

The length of BC = X =  17
