87

You can add up the angles that are labeled(73,110,and 90 because of the right angle) and get 273.

For a quadrilateral, all of the angles add up to 360.

So, subtract 360-273.

You get 87.

Hope this helps:)

Scale a rectangle that has length 9 inches and width 17 inches by the scale factor determine the dimensions of the scaled rectan
emmasim [6.3K]

Answer:

The dimensions of the scaled rectangle are

6.3\ in of length by 11.9\ in of width

Step-by-step explanation:

we know that

The scale factor is equal to 70\%

Remember that

70\%=70/100=0.70

The scale factor is less than 1

so

the dilation is a reduction

To find the dimensions of the scaled rectangle multiply the dimensions of the original rectangle by the scale factor

9*0.7=6.3\ in

17*0.7=11.9\ in
