What is the length of the third side of the window frame below?

(figure is not drawn to scale.)

15 inches
27 inches
25 inches
32 inches

a=15

Step-by-step explanation:

Nice you can take your time now XD

c²-a²=b²

39²-36²=a²

1521-1296=a²

a²=225

a²=√225

a=15

Too easy! :D

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
