Answer:
12) just plug in the numbers to the equation
C = (-4,5) D = (-2,3)
11) 8.426
10) 3, 4, 5
level 3-4) 24
Step-by-step explanation:
11) 7^2 + 11^2 = c^2
49 + 22 = c^2
√71 = √c^2
c = 8.426
10) 3, 4, 5 is a special right triangle but
3^2 + 4^2 = 5^2
25 = 25
level 3-4)
7^2 + h^2 = 25^2
49 + h^2 = 625
√h^2 = √576
h = 24
