In right triangle ABC, ∠A is a right angle, m∠B= 44∘ and AC=10. What is the measurement of BC

BC = 14.4

Step-by-step explanation:

First, draw the triangle, just like what I did (see the picture below).

Second, to find BC, we need to use trigonometry. Tan doesn't work because we're not looking for AB, and cos doesn't work because we don't have AB to find CB. So we are gonna use sin, which is possible because we have AC.

Remember: SOHCAHTOA, sin = opposite/hypotenuse, cos = adjecent/hypotenuse, tan = opposite/adjacent.

Let's write an equation:

Solve for AB:

Isolate the AB:

Which if plugged in a calculator, gives us ≈

40 because it’s just a little longer than 32 feet

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
