Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle (
).
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
It's a lot like solving equations.
3b-7 < 32
Add 7 to each side.
3b < 39
Divide by 3 on each side.
b < 13
Hope this helps :)
Answer:
65 = 6x + 7
6x = 58
x = 9.6666666...
65 + y + 9 = 180
y = 106

You 'lost' 100 dollars in sales and liquid cash. However, you are only missing 30 dollars.
Answer:
$62,005.34
Step-by-step explanation:
If the interest rate is 12.78% compounded monthly, we can use the formula a = p(1+r/n)^nt
where a is the final value to be paid, p is the inicial value, r is the interest rate, n is the number of months in a year and t is the time in years
So, the total debt will be:
y = 4878 * (1+0.1278/12)^240 = $62,005.34
