Ответ:
18.20/213 = x/514
This is because we are looking for the amount of money made after 514 hours of work. That is represented by the variable "x", but we know the amount of hours work, so they are lined up together. Cross multiply the values. 18.2 * 514 is 9,354.8. 213 * x is 213x. So, you are left with 9,354.8 = 213x. Now, divide each side by 213 to isolate the "x". 9,354.8/213 is 43.9192488 and other numbers behind it or 43.92 when rounded to the nearest hundredth. x ≈ 43.92. Daniel would make $43.92 if he worked for 514 hours.
Ответ:
Angle C is 34
Angle A is 90 (that little box indicates 90)
34+90=124
180-124=56
Ange B is 56 degrees.
Hope this helps!!
