Because all consecutive angles in a parallelogram are supplementary, m∠SVU = 180 - 57 = 123°.

Step-by-step explanation:

In a parallelogram, sum of adjacent angles is 180

∠TSV + ∠SVU = 180

57 + ∠SVU = 180

∠SVU = 180 - 57

∠SVU = 123°

11

step-by-step explanation:

32.50-7.50=25

225/25=11

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
