Answer:
<h3><em>
isosceles</em></h3>
An isosceles triangle is a triangle that has two sides of equal length.
An acute triangle is a triangle with three acute angles (less than 90°).
A scalene triangle has all its sides of different lengths. Equivalently, it has all angles of different measure.
An equilateral triangle is a triangle in which all three sides are equal.
Answer:
the first equation is the total legs on one dog being added together with 2 other total dog legs. The second equation is the number of dogs multiplied by the total number of legs on one dog. Either way both equation show 3 dogs with 4 legs each.
we have
1 donut -----> 570 calories
7 donuts ----> 600 calories
7 donuts ----> 510 calories
4 donuts ----> 480 calories
3 donuts ----> 400 calories
so
total donuts=1+7+7+4+3=22 donuts
the means is equal to
mean=(1*700+7*600+7*510+4*480+3*300)/22
mean=11,460/22
<h2>mean=521 calories</h2>
Part 2
Find out the median
order the data set from less to greater
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
the median is the middle of the data set
400 400 400 480 480 480 480 510 510 510 510 510 510 510 570 600 600 600 600 600 600 600
<h2>the median is 510 calories</h2>

Answer:
29
Step-by-step explanation:
From the point where the chords cross, the product of lengths to the circle intercepts is the same for both chords:
LB·LD = LC·LE
10·18 = 9·LE
LE = 180/9 = 20
The the measure of CE is ...
CE = LC +LE = 9 + 20
CE = 29
