The expression to find the value of the final angle of the triangle will be 180° - 40° - α.
<h3>How to solve the triangle?</h3>
Your information is incomplete as the triangle isn't attached. Therefore, an overview will be given.
Firstly, it's important to know that the total angle in a triangle is 180°. A triangle has three sides. In this case, angle B is given as α.
Let's assume that another angle is given as 40°. Therefore, the expression to find the value of the final angle will be 180° - 40° - α

Step-by-step explanation:

Carey earns c hourly
Anderson earns $6 hourly which is also 1+ c/2
So, 6=1+c/2
12=2+c
c=$10
<span>Carey earns $10 hourly</span>
So the problem ask to simplify the trigonometric function in your problem and base on the expression and using the theory in simplifying trigonometric function, the answer would be letter B. 2 sec^2 theta. I hope you are satisfied with my answer and feel free to ask for more
