Answer:
you dont have a picture of the triangle
Step-by-step explanation:
7
using the distance formula
√(4- -3)^2 + (4-4)^2
√49
x=12
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + x^2 = 15^2
81 + x^2 = 225
Subtract 81 from each side
x^2 =225-81
x^2 =144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x = 1
To dilate the figure ADL by the scale factor of 2
To the scale factor of 2, means that all the coordinates 2 times larger
So multiply the coordinates by the 2.
A (-1,-1) -> ( -1*2 , -1*2 ) -> (-2, -2)
D (0,2) -> ( 0*2 , 2*2 ) -> (0, 4)
L (3,1) -> ( 3*2 , 1*2 ) -> (6, 2)
∆ADL dilated by the scale factor of two = A'(-2, -2), D'(0, 4), L'(6, 2)
