Hello!
First you have to find the ratio
To find this you put the sides of the triangles in a ratio and simplify it
Make sure you do the same side on each triangle
12 : 8
6:4
3:2
The ratio is 3:2
We do not know all three sides so we can use the SSS postulate
This tells use the answer is the SAS postulate with a ratio of 3:2
The answer is D) SAS; 3:2
Hope this helps!
K = Kate's age nowJ = Joey's age nowK+5 = Kate's age in 5 yearsJ+5 = Joey's age in 5 years From the first sentenceK+5 = 2(J+5) From the second sentenceK=J+11 So our system of equations isK+5 = 2(J+5)K=J+11 The first equation is equivalent toK+5 = 2J+10or by rearranging termsK-2J=5 The second equation is equivalent toK-J=11 This gives us K-2J=5K-J=11 Using the elimination method, we need to multiply one of the equations by a factor such that we can eliminate one of the variables. This means we want one of the variables to have coefficients which are the same magnitude but opposite signs. We can do this by multiplying the 1st equation by -1. This give us -K+2J=-5 K - J = 11 Now add these two equations together, term by term. This gives usJ=6 So Joey is 6 years old now.
Answer:
Circle A= 
Circle B =
Step-by-step explanation:
Circumference of a circle =
Since you are given the radius, you put it in place of r
Circle A = 
Circle B=

Answer: Choice C, Ro, 270 </h3>
270 degree counterclockwise rotation around the origin
=============================================================
Check out the diagram below. In the diagram, I only focus on points A and A'.
We have A = (-3,4) move to A ' = (4, 3). We see the x and y coordinates swap places. Then the new second coordinate -3 becomes positive, or it has flipped sign. So the rule applied here is 
which describes a 90 degree clockwise rotation; which is equivalent to a 270 degree counterclockwise rotation
The other points follow the same idea.
It’s either A or D but maybe D
