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

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
