Option B: 3 is the right answer
Step-by-step explanation:
If y varies directly as x, it can be expressed as:
y ∝ x
If the values in table are directly proportional then the value of k should be same for all pairs.
the table is directly proportional and the value of k is 3
Hence,

Sine theta almost-equals 0. 9511 and tangent theta will almost equals
3. 0780
<h3 /><h3>What are sin theta,cos theta, and tan theta in trigonometry?</h3>It is given that-
The cosine theta have the value =0.3090.
We can be write as,
cos∅=0.9090
To find the value of theta, We will take cosine function of the value 0.3090
This will make the cosine angle as arc cosine. Thus,
∅=(0.3090)
Solve it further as,
∅=72°
Hence the value of the angle is 72 degrees.
Use this value to find the angle of sin theta and tangent theta.
The value of sine theta,
sin 72°=0.9511
Hence, the value of sine theta is 0.9511.
The value of tangent theta,
tan 72°=3.078.
Hence, the value of tangent theta is 3.078.
Hence,
- The value of sine theta is 0.9511.
- The value of tangent theta is 3.078.
