Answer:
A line is at a degree of 180, so the line 170 is on can give you the degree of the smallest angle: 10. A traingel has a total degree of 180, so 125 + 10 = 135. Take 180 and subtract 135 to get x = 45º
Step-by-step explanation:
Let the two required numbers be x and y, then x - y = 176, thus y = x - 176.
Let the product of the two numbers be represented by

For the product to be minimum,


Thus, y = 88 - 176 = -88
Therefore, the two numbers are 88 and -88.
5 students used 1/8 each
5 · 1/8 = 5/8
Subtract 5/8 from 2 3/4 to get your answer
First, make it the same denominator: 8
2 3/4 = 2 6/8
2 6/8 - 5/8 = 2 1/8
There is about 2 yarn left. Exact amount left: 2 1/8
