Answer:
This is an Obtuse triangle.
Step-by-step explanation:
A Equilateral Triangle is a triangle where all sides are equal. Here all sides are different so it is not an Equilateral Triangle.
Isosceles triangle is a triangle that has 2 sides that are equal. Here all sides are different therefore this is not an Isosceles triangle.
A right angled triangle is a triangle whose sides satisfy the following equality.
Lets say A triangle has sides a, b and c. Where c is the highest value.
Then,
Lets substitute the values to the above equation to see whether it the triangle we are given satisfies the above equality,
=
=

Therefore,
≠
=
≤
Therefore, This is an Obtuse triangle.
Answer:
Try Khan Academy. They give lots of expression to find the greatest difference. It always helps me in this situation.
Step-by-step explanation:
<em>C = I</em>
<em>150p + 525 = 325p</em>
<em> 525 = 175p</em>
p = 3
If the groups are all made up of 10 pennies and she added 5 groups, then
5 x 10 = 50
Which means she added 50 pennies to the jar and now has 150 pennies. :)
