x = 7
Step-by-step explanation:
( x +16)° = (4x - 5)°
x + 16 = 4x - x
16 + 5 = 4x - x
21 = 3x
7= x
hence, x =7
The cost of delivering an item that weighs 4/5 of a pound?$21.60.
<h3>How to find the delivery cost?</h3>
Let x = the number of pounds
Thus, we can say that;
Cost = 25x * 1.08
Since we want to find the cost of delivering an item that weighs 4/5 of a pound, the we will put 4/5 for x to get;
Cost = (25 * 4/5) * 1.08
Cost = 20 * 1.08
Cost = 21.6
The delivery cost would be $21.60.

Answer:
54.8
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2.
Plug the given values in to get 61^2+b^2=82^2
61^2 is 3,721 and 82^2 is 6,724.
6,724-3,721 is 3,003.
The square root of 3,003, rounded to a reasonable value, is 54.8.
The length of AC is 54.8.
