Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 13², so
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = = 5
Answer:
820
Step-by-step explanation:
Hi so if your area is 4756, the base would be 820
P(x) = amount made - cost
p(x) = 20x-7x-10
p(x) = 13x -10
5,8,13 is not possible because when you add 5 and 8, they equal 13, the longest side/hypotenuse. Basically, when your two shorter side lengths add to be equal to or less than the longest side length, it’s not a triangle
Make them equal to each other because they are vertical angles.
6x-4=5x+5
x=9
