1 answer:
enot [183]2 years ago

Answer:

100°

Step-by-step explanation:

First, remember that flat angles are always 180°,

So the angle of B is 40° because they form that kind of angle.

Now, you can notice that both sides of the triangle have the same value.

That means the angle is the same too.

So, the third angle is also 40°

Last but not least the addition of all angles in a triangle is always 180°

With that in mind we just solve the next equation:

40° + 40° + a° = 180

a° = |80 - 80

a = 100°

And that is how we find the answer, hope it was helpful ;)

Answer 37, 38, and 39 and make sure to answer with either the letter or with one of the answers shown! SHOW YOUR WORK PLEASE!!
ollegr [7]

Answer:

I didn't even realize until I had written all of the answers down that they are all <u><em>C.</em></u>

37 = C. <u>15%</u>

38 = C. <u>2x^{3}</u>

39 = C. <u>48</u>

Step-by-step explanation:

37: I used process of elimination to figure out which percentage of decrease it was by just multiplying 42 by each percentage until I got 6.3 which is what you need to subtract from 42 to get 35.7, so the answer is C, or 15%.

38: A coefficient is the number that is being multiplied by the variable, which in this case is "x". So whatever answer involves "2x" is the correct answer. Therefore the answer is C, or <u>2x^{3}.</u>

39: You have to add the amount of money Henry paid for painting supplies and how much profit he mad to figure out how much money he really made. 400 + 560 = 960 and he charges $20 for each painting so you need to divide 960/20 to get your answer, which is C, or 48.
