What is one method to find the measure of angle b?

A.

Step-by-step explanation:

Since we have two sides, we can use the Pythagorean Theorem to find the other side, and use any trig function to find B. For the option B, Nowhere in the problem does it state an angle except the 90 degree angle. So we can't find an angle without trig functions. For option C, it wants to trick you. The formula for cosine is adj/hyp, not opp/hyp. The opp of B is 8, and the hyp is root 89. So that function is actually sine, not cosine.

A is the right one

Step-by-step explanation:

it is right on edge

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
