We are given that
In right triangle ABC, if angle A is 90 degrees, angle C is 34 degrees, and AC is 71.4, find BC.
Solution
We will first draw a diagram to illustrate the information
Above we want to find x
The method to use is SOHCAH
From the right angle triangle above we have above, we have the adjacent side and we want to find the hypotenus, so we use cosine
i.e

We need to solve for x here

Thus, |BC| = 86.1 (to the nearest tenth
It is D
Because the amount of the inside angles of an triangle are equal to 180 degrees
And a straight line is 180 degrees
Answer:
Let y be the total earns of jason
where x is the number of hours jason works that day
y=15x ×40
y=600x
total earns of jason y = 600x
