if cos∠b = sin∠a and m∠a = 32°, what is the measure of ∠b?
32
58
90
148

  58

Step-by-step explanation:

  sin(A) = cos(90°-A) = cos(B)

  90° -32° = B

  58° = B

You can also work this on your calculator:

  cos(B) = sin(32°)

  B = cos⁻¹(sin(32°)) = 58°

It is 58 degrees.

Step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
