Which of the following best completes the proof showing that δwxz ~ δxyz? triangles wxz and xyz that share side xz with right angle xzw, wz equals 16, xz equals 12, and yz equals 9 since segment xz is perpendicular to segment wy, angles wzx and xzy are both right angles and congruent. the proportion shows the corresponding sides are proportional, so the triangles are similar by the sas similarity postulate.
a)16 over 12 equals 9 over 12
b)16 over 12 equals 12 over 9
c)12 over 12 equals 16 over 9
d)12 over 16 equals 16 over 9

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
