If a math problem asks you about how much something is for division , will the problem make you estimate?
postnew [5]

Answer:

Yes

I hope this answers your question!

Step-by-step explanation:

How do you estimate a division problem?

You can use multiplication to check your division answer this way.

1) Do the division problem.

2) Multiply the quotient times the divisor.

3) If there is a remainder, add it to the multiplication product.

4) Compare this answer to the dividend. They should be the same number (630 = 630).

PLS HELP I WILL GIVE YOU A BRAINLIST AND A THANK YOU!!!!

Answer:

75

Step-by-step explanation:

We have a 90 degree angle and a 15 degree angle that add up to 105. The angle that is missing can be found by doing 180 - 105 = 75 (since it's a straight line). X is vertical from the 75 degree angle, so 75 is your answer.
