Answer:

B. 10 Degrees.

Step-by-step explanation:

The degrees of the angles on a triangle must have a sum of 180 degrees.

100 + 70 = 170.

180 - 170 = 10.

This is how you know 10 degrees is what the third angle must be.

100 + 70 + 10 = 180.

So, B is your answer.

Alice has 1/5 as many miniature cars as Sylvester has Sylvester has 35 miniature cars how many miniature cars does alic have?

const2013 [10]

The answer is 7. Since Alice has 1/5 as many cars as Sylvester. You multiply 1/5 by how many cars Sylvester has. Sylvester has 35 cars, so you would do 35 times 1/5 or 35 divided by 5 (multiply by 1/5 and divided by 5 are the same thing) and you would get your answer of 7.
