△abc is similar to △pqr. also, angle a measures 35° and angle b measures 50°. what is the measure of angle r? enter your answer in the box.

The inside of a triangle HAS to equal to 180 degrees no matter the shape or size. For triangle abc since angle a is 35 degrees and b is 50, that means that c is 95 degrees. Since both triangle are similar, angle r is going to also be 95.

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.
