The longer base of an isosceles trapezoid measures 23 ft. The nonparallel sides measure 9 ft, and the base angles measure 80°. F
snow_lady [41]
Check the picture.

Consider the triangle DAB, with |DA|=9 ft, |AB|=23 ft and m(DAB)=80°.

To find the length of the diagonal, |DB|, we use the cosine law:

|DB|^{2}= |DA|^{2} + |DA|^{2} -2|DA|*|AB|*cos(DAB)

=9^{2}+23^{2}-2*9*2*(0.173)=81+529-6.228=603.7

Thus, |DB|= \sqrt{603.7}=24.6 (ft)


Answer: 24.6 ft

Use the Distributive Property to solve the equation. 2x−4​(x−3​)=−8+5x-8
andrew11 [14]

Answer:

x = 4

Step-by-step explanation:

Distributive Property: a(b + c) = (a*b) + (a*c)

           2x - 4(x - 3) = -8 + 5x - 8

2x + x * (-4) - 3*(-4) = -8 + 5x - 8

          2x - 4x + 12  = -8 + 5x - 8    

   2x -  4x - 5x + 12 = -8 - 8

               -7x  + 12  = -16

                       -7x  = -16  -12

                      -7x   = -28

                          x = -28/-7

x = 4

Ciana wants to buy a shirt that regularly cost 30$.It is on sale for 40$ off. How much is Ciana saving on the shirt?Please help
DerKrebs [107]

Answer:

I think you meant 40% off. If so...

Step-by-step explanation:

First, you have to turn 40 into a decimal - .40.

Then you multiply 30*.40 and get 12.

Subtract 12 from 30 since you are saving 12 dollars.

This means you spend $18 and saved $12.

So, your final answer would be $12.

Hope this helps :)
