Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = = 60
Answer:

Answer:
0 less-than-or-equal-to x less-than-or-equal-to 20;
0 less-than-or-equal-to y less-than-or-equal-to 60
Step-by-step explanation:
The range in values of x is from 2 to 17, so a suitable window would be 0 to 20.
The range in values of y is from 5 to 53, so a suitable window would be 0 to 60.
0 ≤ x ≤ 20
0 ≤ y ≤ 60
