Ineed to find the missing side to this shape. (file attached)

Draw a line parallel to distance between two buildings

then we get triangle in which side are

Hypotenuse=15

opposite=20-8

=12

adjacent=?

by Pythagoras,

(hypotenuse)²=(Opposite)²+(adjacent)²

15²=12²+adj²

225-144=adj²

81=adj²

9=adjacent

so the distance between two buildings is 9ft

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
