Answer: The remaining angle must be 90, side BC = 17, side AC = 39
Explanation:
To find the remaining angle of this triangle, you may do 180 - (24+66) = 90, since the sum of angles in any triangle must equal to 180.
To find the remaining sides, you may use the sine rule to find BC:
sin(Angle)/opposing side = sin(Angle)/opposing side
1) sin90/43 = sin24/x
2) 1/43 = 0.4067/x
3) x = 17.48
4) x ≈ 17
You may also use the sine rule to find side AC:
1) sin90/43 = sin66/x
2) 1/43 = 0.9135/x
3) x = 39.28
4) x ≈ 39

Answer:
1/3y-7
Step-by-step explanation:
For these kinds of problems you want to combine like terms. 2/3y and -1/3y are like terms, and when adding them together, or subtracting 1/3y from 2/3y, you get 1/3y. -3 and -4 are like terms, and adding them together gives you -7. The final expression can be written as 1/3y-7.
When y=-15, x=-20. So subtract x from y, you will get that y= 0 and x=-5. Add 12 to both and you have your answer, x=7 and y=12
Hi, Globabypatricia! :)
All the time worked past 31 hours gets paid 1.3 times.
He worked 4 hours at such a rate.
31+4(1.3)
31+5.2
=36.2
Paid as if he worked 36.2 at a normal rate.
To find his normal wage, divide 448.88 by 36.2
448.88/36.2
=12.40
His normal wage is $12.40.
To check:
12.40*31=384.40
12.40*1.3=16.12
16.12*4=64.48
384.40+64.48
=$448.88
Hope this helps.
