Is a triangle with angle measure 40°,30°,and 120° possible?

The total measure of a triangle's angles is always 180 degrees exactly. A triangle with 40, 30, and 120 degree angles has a total of 190 degrees, as 40 + 30 + 120 = 190. Because 190 degrees is greater than 180 degrees, it is not possible.

Iwould say false, not positive but if prices went up for both stores, technically there will be less buyers?

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.
