Answer:
They are similar by SAS
Step-by-step explanation:
They are similar by SAS
60/42 = 40/28
also the parallel lines means that the angle they create by intersecting with the top line is equal
so SAS
Answer:
Step-by-step explanation:
We need to find the equation of the circle. First, the formula:
Where (h,k) is the center and r is the radius
The center is (5,-4), so we can say:
Now, to find the radius, we can use the distance formula to find distance between (5,4) and (-3,2).
The distance formula is
Where
x_1 = 5
x_2 = -3
y_1 = 4
y_2 = 2
Plugging in, we get:
Hence, the radius is 10 and we can write the equation of circle as:
Answer:
no
Step-by-step explain why
because they have to be the same numbers
