Answer:

Step-by-step explanation:

given tanB= 4/3

so sinB=4/5

n cosB=3/5

given BC=15

BA=BC*cosB

=15*3/5

=9

AC=BC*sinA

=15*4/5

=12

Triangle ABC and DBE are similar by AAA

DB= BA-AD

=9-3

=6

DB/BA=DE/AC

6/9=DE/12

DE=12*6/9

=8

You walk into a store that is closing. the pants normally cost $60.00 but it is discounted 75% they are also taking additional 2
eimsori [14]

Answer:

The final cost of the pants is $ 12.

Step-by-step explanation:

Given that at a store that is closing the pants normally cost $ 60.00 but it is discounted 75%, and they are also taking an additional 20% off, to determine what is the final price for the pants, the following calculation must be performed:

100 - 20 = 80

(60 - (60 x 0.75)) x 0.80 = X

(60 - 45) x 0.80 = X

15 x 0.80 = X

12 = X

Thus, the final cost of the pants is $ 12.

Can someone explain how to do this? I don't get it.
mihalych1998 [28]

Answer: I think 91.9

Step-by-step explanation:

If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9

Sorry if that’s not right! I just wanted to take a crack at it.
