When given 3 triangle sides, to determine if the triangle is acute right or obtuse
square all 3 sides
sum the squares of the 2 shortest sides
compare this sum to the square of the 3rd side
if sum > 3rd side squared it's an acute triangle
if sum = 3rd side squared it's a right triangle
if sum < 3rd side squared it's an obtuse triangle
24 32 42
24*24 = 576
32*32 = 1,024
42*42 = 1,764
Sum of the square of 2 shortest sides = 1,600
Since 1,600 < 1,764 these sides form an obtuse triangle.

Ok so subtract 25 minutes from the overall time. Then divide 125 minutes by 50 to get 2.5. So your lamb weighed 2.5kilos
Answer:
10.2
Step-by-step explanation:
The perimeter of a square is 4 times the length of its side. Therefore, the answer to this problem is 4x+3.
When adding a negative number to a negative number you are actually subtracting it., so the number is a larger negative number
