Two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle true or false

I believe the answer to that is true but im not to sure but i mean they just hae to have the same angle measure

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.
