We know that
<span>the isosceles triangle has two equal sides
</span>
<span>let's analyze two cases
</span>
first case
perimeter=22 cm
<span>let's suppose that the known side of 6 cm is one of the two equal sides
</span>perimeter=6+6+x
22=6+6+x-----> x=22-12----> x=10 cm
answer first case
<span>the possible lengths of the other two sides are
</span>6 cm
10 cm
second case
let's suppose that the known side of 6 cm is the side that is not equal
perimeter=22 cm
perimeter=6+x+x
22=6+x+x----> 2x=22-6----> 2x=16-----> x=8 cm
answer second case
the possible lengths of the other two sides are
8 cm
8 cm
2x + 4 = 3x - 10
-2x and +10 to both sides
14 = x
the answer is x = 14
Answer:
90
Step-by-step explanation:
To find the mode you need to put all the numbers given in order, then count them and decide which number occurs the most.
Given the number you have here, we're going to put them in order, like so,
78, 78, 83, 85, 89, 91, 95, 98 (they were in order already)
Now we see which number occurs the most.
The number would be 78
