Answer:
h= 4
Step-by-step explanation:
A= 1/2(b)(h)
10= 1/2(5)(h)
10= 2.5h
/2.5 /2.5
h= 4
Let me help you!
Ok, so before I give you the answer, which is very simple, I will first show you how to answer questions like this in the future.
In the variable declaration, the array "numbers[]" has been declared as an integer. The values of the array "numbers[]" are: <span>83, 62, 77, 97, 88; respectively, the values are equivalent to: 0, 1, 2, 3, 4 which makes the range of array "numbers[]": 5.
To make it clearer:
</span>numbers[0] = 83
numbers[1] = 62
numbers[2] = 77
numbers[3] = 97 <---- This is what we are looking for!
numbers[4] = 88
*** By the way, when counting the range, we don't start at 1, we start at 0. That's why even if the range is 5, the last value is 4.
Therefore, the answer is: 3 or numbers[3].
