Okay, the total is 69 units.
(3y)+(12)+(y+1)+(2y+3)+(11)=69
Combine like terms
6y+27=69
Subtract 27 from both sides.
69-27=42
Divide by 6 on both sides
42/6=7
y=7
Plug it into the length of AB
2(7)+3
14+3
length of AB=17
C because i did it and got it right
The answer is A because it has or in the sentence
Pick a pair of sides whose length you DO know. Whatever their ratio is, every pair of sides has the same ratio IF the figures are similar.
Like if you find a pair of corresponding sides and the big one is double the length of the small one, then the big one is double the length of the small one for EVERY pair of sides in those two figures.
Answer:
the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
