Find the value of (x), when a penatagon has
the following interior angles, 90 degrees, 125
degress, 2x degrees, 125 degrees and 2x
degrees

x=50

Step-by-step explanation:

the sum of interior angles in a pentagon is 540.

So, 90+125+2x+125+2x=540       90+125+125=340

340+4x=540   540-340= 200

4x=200    200/4=50

x=50

$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
