What is m2b? round the value to the nearest degree. [1] • 29 cm a 20 cm b

Your question is so confused. Are you looking for the measure of angle B?

Below is my work on how to find the angle B.

B = 46°

Step-by-step explanation:

Cos(B) = Adj./Hypo.

Cos(B) = AB/BC

Cos(B) = 20/29

Cos(B) = 0.6897

B = Cos^-1(0.6897)

B = 46°

For this case we have to define trigonometric relations of rectangular triangles that the cosine of an angle is given by the leg adjacent to the angle on the hypotenuse of the triangle. Then, according to the figure we have:

So:

Rounding off we have that B is 46 degrees

46 degrees

both equations and proportions are better.
