Answer:
‹A = 141°
‹B = 28°
‹C = 11°
*These angles are rounded to the nearest whole*
Step-by-step explanation:
Because you are only given sides you can find an individual angle measures with the inverse law of cosines.
Remember the side opposite of the angle corresponds to that angle.
a² = b² + c² - 2bc cos(A) →
A = cos⁻¹ (a² - b² - c² / -2bc)
b² = a² + c² - 2ac cos(B) →
B = cos⁻¹ (b² - a² - c² / -2ac)
c² = a² + b² - 2ab cos(C) →
C = cos⁻¹ (c² - a² - b² / -2ab)
Yes, it is also a square number
I usually just type sqrt of ___. It works.

sorry if I couldn't help
4300 is your principal
1.8% interest rate (change it into decimal form; 0.018)
2 years is our time
We'll now multiply our variables.
4300 x 0.018 x 2 = 154.80
This shows that in 2 years at their interest rate that they have earned 154.80.
We will add the $154.80 to the original borrowed amount of 4300.
$4454.80 will be how much they will owe after 2 years.
To find out the amount in 15 months we'll divide 15 months by 12 and we get 1.25 and now we multiply the numbers again.
4300 x 0.018 x 1.25 = 96.75
They will pay $96.75 in interest within 15 months and we'll add it to the 4300.
$4397 will be how much they will pay after 15 months.
