<span>find the range. [15(35)]+[12(60)] and this will be your high end. now do it again but at the low end [15(20)]+[12(30)] and this will be your low end. now you have the max amount the price would be and the lowest amount of the price. now look at your answers and see what is within that range and what isn't and there's your answer.</span>
Complementary angles are angles whose measure add up to 90°.
So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.
Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.
Angles who has a sum of 180° are called supplementary angles.
The first answer would be to take 182.50-67 and it gives you 115.50 which is number one.
2. To solve X/0.4=10 you need to get X by itself since it's being stuck by division you multiply both sides by 0.4 which is the third answer down. Hope this helps!
I am probably entirely wrong but I think 101.8? Sorry but I am stupid.
