Step-by-step explanation:

just add all the given angles and equate it with 540° and then find x

x/2 + x/2 + x - 25 + 100 + x - 15 = 540°

3x + 60 = 540°

3x = 540 - 60

x = 480/3

x = 160°

on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.

works as a florist and worked 12 hours last week and earned $98. At that rate, how much will she earn this weekend if she works

kotykmax [81]

Answer:

$114.3

Step-by-step explanation:

Number of hours worked last week = 12hrs

Amount earned for her work hours = $98

The rate at which she earned = ?

Rate = $\frac{amount earned }{total work hour}$

Rate = $\frac{98}{12}$ = $8.17/hr

Now;

Since the total hours she worked during the weekend = 14hrs

Amount earned = $8.17/hr x 14hrs = $114.3
