f the measure of angle BCD is 67.4°, the measure of angle ABC is °. If the length of base AB is 80 feet, the length of DC is feet.

Step-by-step explanation:

Given

and side length DC

 Calculating

First, calculate

--- angles in a triang;e

So:

Collect like terms

So:

Calculating DC

First, calculate EC using Pythagoras theorem.

Collect like terms

Take square roots

Length DC is:

Where

So:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
