Answer:

20°

Step-by-step explanation:

According to the question, pair of supplementary angles are x and 8x

since they are supplementary, their sum is equal to 180°

x+ 8x = 180°

9x= 180°

x= 180°/9

x= 20°

Two trapezoids below are similar what is the length of RS?

stepladder [879]

9514 1404 393

Answer:

11.5 m

Step-by-step explanation:

The fact that the figures are similar means the side lengths are proportional:

RS/QT = BC/AD

RS/(7 m) = (2.3 m)/(1.4 m)

RS = (7 m)(2.3/1.4) . . . . . . multiply by 7 m

RS = 11.5 m
