cos B= 0.5299

hav B = 0.2351

To find the value of angle B, we can use the inverse cosine function (also known as arccosine or cos^-1) which gives us the angle whose cosine is equal to the given value.

In this case, cos(B) = 0.5299. To find the value of angle B, we need to take the inverse cosine of 0.5299.

cos^(-1)(0.5299) = B

Using a scientific calculator or trigonometric table, you can find that the inverse cosine of 0.5299 is approximately 57.15 degrees.

Therefore, angle B is approximately 57.15 degrees.
