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
Answer:
The desired distance is 15 units.
Step-by-step explanation:
Note how x increases from 1 to 10 and y from 0 to 12 at the same time.
Using the Pythagorean Theorem, we find that the distance between the two points is the length of the hypotenuse, which is
d = √[ (10 - 1)^2 + (12 - 0)^2 ], or d = √ [81 + 144] = 225 = +15
The desired distance is 15 units.
