He was using an isosceles right triangle.
Both legs of an isosceles triangle are the same length, so knowing that when the shadow of the triangle was the same height as the triangle, then he knew that the shadow of an object would also be the same as it's height.
Answer:
1.02n
Step-by-step explanation:
A simplified version of this expression would be the following
1.02n
This is basically adding the n variables together. We do this by adding a 1 to the number being multiplied to n. This would basically add the 2% on top of what the original pay per hour is. We can prove that these two expressions are the same by substituting n for 10 in both expressions and solving them.
1.02n
1.02 * 10 = 10.2
n + 0.02n
10 + 0.02*10
10 + 0.2 = 10.2
Answer:

Step-by-step explanation:
Answer:
the numbers are 31 and 14
Step-by-step explanation:
since the larger number is 17 more than the smaller number,

smaller number= x-17
x-17+x=45
2x=45+17
2x=62
x=31
x-17=31-17
Answer:
