Answer:
Step-by-step explanation:
Each 90° clockwise turn takes a point (x,y) and transforms it to (y,-x). For a 180° turn you would do this process twice in a row; for a 270° turn, three times in a row.
Multiply 3x*4=12x -6*4=-24 so 12x-24=24 add 24 and it would be 12x=48 divide by 12 and x=4
Answer:
25
Step-by-step explanation:
(0,0) to (12,0) => the distance = 12
(12,0) to(7,12) => the distance =
√[(12-0)²+(7-12)²]=√(144+5) =√169 = 13
so, the total distance = 12+13 = 25
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = 
, then
cos30° = 
= 
= 
= ( cross- multiply )
2 AC = 12
× = 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
