What is the number down their?
Answer:
60
Step-by-step explanation:
perimeter (p) = 8 + 17 + 15 = 40
semi-perimeter (s) = p/2 = 20
Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.
Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
The answer is -25
3-8=-5
-5*5=-25
The opposite angles theorem says that the opposite angles are equal. Thus:

Answer: The equation that made true the opposite angles theorem is the one that is at letter B.
Answer:
5355
Step-by-step explanation:
if the height is 612 and traignle has 3 sides so then 10710 is in the total so it has to be big and if the right triangle is 90 degrees
it equals to 5355
