3) . Ddraw the radius to the right side of the chord. So you formed a right triangleNow let's apply Pythagoras
3.6² + 5.5²= x² ==> x = 6.57 ≈ 6.6
4) same logic but the other leg = x/2 you will find
x² = 133/4 & x =5.766≈ 5.8
5) arc ab = arc de (1st proposition)
If you help me I would help you to
One circle is 360 degrees. Then, 360/5 = 72 degrees per slice of watermelon.
<span>Let us start with the schnauzers, the easiest one to imagine. Let us assume that there were x number of schnauzers.
Scottie's are 3 more than schnauzers. So their number is x+3
Wire haired terriers are 5 less than twice the number of schnauzers.
So their number is 2x -5 (2x for twice the number of schnauzers)
Now add all these numbers.
That is x + x+3 + 2x-5 = 4x -2
The total number of dogs, 78, is given in the question
Now we know that 4x -2 =78
4x = 78 +2
= 80
Therefore x = 80/4
= 20.
So there were 20 schnauzers, 23 Scottie’s and 35 wire haired terriers</span>
