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)

Step-by-step explanation:
Answer:
10 5/12
When the numerator is larger than the denominator, we take groups of whole fractions (The numerator and denominator are equal) and add 1 to the whole number for each group. Whatever remains when we no longer have the numerator larger than the denominator is left as a fraction.
Step-by-step explanation:
6 3/4 + 3 2/3
We need to get a common denominator
The common denominator is 12
We need to rename the fractional parts to out of 12
6 3/4 = 6 3/4*3/3 = 6 9/12
3 2/3 = 3 2/3*4/4 = 3 8/12
6 9/12+ 3 8/12
9 17/12
But the numerator is larger than the denominator
We take 12/12 from the fraction and add it to the whole number
9 17/12-12/12 +1
9+1 5/12
10 5/12
