**Answer:**

maybe it's 10.because c is 10,b is 10,and so as s.

hence s is 10 also.

The 3 inside angles of a triangle need to equal 180 degrees.

You are given 2 of the angles that are 60 degrees each

The total of the 2 angles you know is 60 + 60 = 120 degrees

So y = 180 - 120 = 60 degrees

**Answer:**

3024 in^3

**Step-by-step explanation:**

Think of the dimensions of this prism as being 18 in by 12 in by 14 in:

V = (18 in)(12 in)(14 in) = 3024 in^3

**Answer:**

The total change in his account is of -$85, that is, a loss of $85

**Step-by-step explanation:**

**We combine these changes.** So

On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.

On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70

On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85

The answer is the first solution...hope this helped?
