Answer:
a. 18
b.144
c.108
Step-by-step explanation:
Using the given, Angle R equal 5x-54 and Angle T is 8u.
Also RS is congruent to ST. Since SR is congruent to ST, their opposite angles are also congruent using base angle theorem. So angle R is equal to Angle T. However, STU is a exterior angle so STU isn't congruent to SRT.
However, we can add , interior angle T, and STU to 180 to find x.
Interior angle T=SRT so interior angle t=5x-54.
Set up equation
b.Plug 18 into 8x
STU=144
c. Using the triangle exterior angle theorem, the exterior angle is equal to the measure of the sum of two non adjacent angles.
Angle S and Angle R are the non adjacent angle to STU.
So we cast up this equation.
plug 18 in for x
s=108

Answer:
$101.25
Step-by-step explanation:
Given:
Jeni works from 8:00 - 3:15 three days
Taking a half-hour unpaid lunch break each day.
she is paid $15 per hour.
Question asked:
what will be her total earnings before tax ?
Solution:
Numbers of hours from 8:00 to 12 = 4 hours
Numbers of hours from 12:00 to 3:00 = 3 hours
Numbers of hours from 3:00 to 3:15 = 15 min = (converting min into hrs)
Total numbers of hours = 4 + 3 +
= 7 + = 7 + 0.25
= 7.25 hours
Unpaid lunch break = half hours = 0.50 hours
Total number of hours for which she is paid = 7.25 - 0.50
= 6.75 hours
By applying unitary method :
In 1 hour she is paid = $15
In 6.75 hours she is paid = 15 6.75 = $101.25
Therefore, her total earnings before tax = $101.25
