B)
E = mc^2
E = 7 * 5^2
E = 7 * 25
E = 175
c)
b = sqrt (c/d)
b = sqrt (100/4)
b = sqrt (25)
b = 5
The value of tangent a in the right triangle in which , cosine a = 0.352 and sine a = 0.936 is 2.659.
<h3>What are the trigonometric ratios?</h3>
Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle. The value of tangent of angle is equal to the ratio of sine of that angle to the cosine of that angle.
![\tan\theta=\dfrac{\sin\theta}{\cos\theta}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7B%5Csin%5Ctheta%7D%7B%5Ccos%5Ctheta%7D)
Here, θ is the angle.
The value of angle given in the problem are,
- Cosine a = 0.352
- Sine a = 0.936.
Put these values in the above fromula as,
![\tan (a)=\dfrac{\sin(a)}{\cos(a)}\\\tan (a)=\dfrac{0.936}{0.352}\\\tan(a)=2.659](https://tex.z-dn.net/?f=%5Ctan%20%28a%29%3D%5Cdfrac%7B%5Csin%28a%29%7D%7B%5Ccos%28a%29%7D%5C%5C%5Ctan%20%28a%29%3D%5Cdfrac%7B0.936%7D%7B0.352%7D%5C%5C%5Ctan%28a%29%3D2.659)
Hence, the value of tangent a in the right triangle in which , cosine a = 0.352 and sine a = 0.936 is 2.659.
