Answer:
- 3
Step-by-step explanation:
using the rule of radicals
× 
⇔ 
simplifying 
when r = 2
= 
= 
= 
× = 4, hence
- 4 = - 3
<span>Given:
C -> Umesh's total charge in dollars.
h -> the number of hours he spends on a job.
Hourly charge =$80 /hr
Charge for h hours = 80*h
fixed charge per job = $50
Therefore, C = 80h +50 is the required equation to find the total charges</span>
If the two angles are congruent then d=b , e=a , and f=c. That means that EF=AC so the equation is x-5=15. so x=20. Hope this helps!!!
Answer:
Step-by-step explanation:
KT because triangles KIT and KET are congruent ( mirror images).
