Answer:
8 cm
Step-by-step explanation:
Two circles of radii 5 cm and 4 cm intersect at two points D and E.
The distance between their centers (points A and C) is 3 cm.
Consider triangle ACD. In this triangle,
AC = 3 cm (distance between centers)
AD = 5 cm (radius of larger circle)
CD = 4 cm (radius of smaller circle)
So, this is right triangle and therefore, AC is the height of isosceles triangle ADE (triangle ADE is isosceles, because AE = AD).
The height of the isosceles triangle drawn to the base is its median, so CD = CE = 4 cm, hence
DE = 4 + 4 = 8 cm

The estimated sum of the numbers fifty-eight (58) and twenty-nine (29) is equal to ninety (90).
<h3>What is the difference between a regular sum and an estimated sum?</h3>
In an estimated sum, the numbers are rounded; on the other hand, in a regular sum, the numbers are not changed.
<h3>What is the estimated sum of 58 and 29?</h3>
1. Round the numbers:
- 58 = 60 as this number is nearest to 60 than to 58.
- 29= 30 because of the same reason explained above.
2. Add the rounded numbers:

<u>The Equation of a Line</u>
The equation of the line in slope-intercept form is:
Where m is the slope and b the y-intercept.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
We are given the points (5,2) and (0,-1), thus:
Operating:
To find the slope-intercept form, we continue to simplify the expression:
Removing the parentheses:
Adding 2:
