It would be 20.4 km because if 1cm is 12km then you just have to multiply 1.7 x 12 = 20.4.
Answer: C
Triangle=36+42+102=180
Answer: B, 120
Step-by-step explanation:
look at x-value 8 and find y-value
Answer:
x = 2/3
DF = 10
scale factor of ΔDEF to ΔXYX is 1:3
Step-by-step explanation:
DF corresponds to XZ and DE corresponds to XY so we can set up a proportion:
6x+6/30 = 8/24
simplify 8/24 to be 1/3
6x+6/30 = 1/3
cross-multiply:
3(6x+6) = 30
18x + 18 = 30
18x = 12
x = 12/18 or 2/3
