c = amount of chocolate donuts
m = amount of maple donuts.
so we know the total in all is 41 donuts, thus c + m = 41.
we also know that whatever c is, m is 25 fewer than that, m = c - 25.
Given that ABC is a right triangle.
The length of AC = 10 and AB = 17
We need to determine the m∠B
<u>The measure of ∠B:</u>
The side opposite to ∠B is AC and the hypotenuse of the triangle is AB
The m∠B can be determined using the trigonometric identity,
where and
Substituting, we get;
Substituting the values, we get;
Taking on both sides of the equation, we have;
Rounding off to the nearest tenth, we get;
Hence, the measure of ∠B is 36.0°
