Hence they are similar
#2
- <A=<H
- And ratio of sides are same
Hence both triangles are similar by SAS property

Answer:
$144.50/8.50 = n
Explanation:
The word each indicates this equation will use division. We know the total is 144.50, so that will be the number being divided. 8.50 is the number 144.50 is divided by. The quotient will be represented by the variable, n.
You can prove a triangle is isosceles by finding the amount of right angles in a triangle. A triangle containing 2 right angles is classified as isosceles.
Answer:
7.21
Step-by-step explanation:
