Answer:
AC = 6 cm
Step-by-step explanation:
First, realize that these are two identical triangles. We just have to use the pythaogrean theorem on one side to find AD or DC, then multiply that by 2 to get AC.
a^2 + b^2 = c^2
8^2 + b^2 = 10^2
64 + b^2 = 100
100 - 64 = b^2
b^2 = 36
b = 6
cosß=z/24
z=cos30°(24)
z=20,78
Answer: 1/3
Step-by-step explanation: The slope goes up 1 and over 3 each time. Rise over run : 1/3
It is 2/4 equal to 1/2 (2.5)
1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91
