2.what is the measure of the unknown angle in the base of this pyramid? 3.what is m

Pretend that unknown angle = x
sum of all angles of a triangle = 180 degrees 
55 + 70 + x = 180
125 + x = 180
 x = 180 - 125
 x = 55
 There you go!!!

The answer to your question is b

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
