9 inches long
9 divided by 10 is .9
multiply it by 10 (to get the length of the purple ribbon) and the answer is 9
Answer:
16
Step-by-step explanation:
Use a special rule: BD^2=AD*DC (the squared height in right triangle drawn to hypotenuse is equal to the product of the parts of hypotenuse on which height divides the hypotenuse) 12^2=9*DC
DC=16
5 squared +12 squared= 13squared 25+144=169
10 + 24 /=/ 28 one common ratio is 5 12 13 this does not match up
15+36= 39 5 12 13 ratio
50 120 and 130 5 12 13 ratio
Answer:
It will always be the case when A and B are opposites
Step-by-step explanation:
sin(x) = -sin(-x) so ...
sin(A -A) = (A -A) = sin(A) -sin(A) = 0
That is, the given expression is true when B=-A.
