Mar 11, 8:54:20 AM ARST is dilated by a scale factor of 2 with center of dilation at point J. If m RST=40
and m_S'R'T'=60, what is the mZRTS?

Submit Answer

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

56 44 2 4

step-by-step explanation:

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.

lr = 24

step-by-step explanation:

note that p is the midpoint of lr. to find the measurement of lr, set the equation:

lr = lp + pr

plug in the corresponding numbers to the corresponding variables:

lr = (15) + (9)

simplify:

lr = 24

24 is your measurement of lr.
