We know that the summation of angles of a triangle is 180°. Then we find angle of C by,m∠A + m∠B + m∠C=180° 80° + 50° + m∠C=180°m∠C=180°- 80°+ 50° m∠C=50°Since we now angle of C, we can use Sine Law in solving for ACsinC/AB=sinB/ACsin50°/6 =sin50°/ACAC=6cmTherefore, AC is equal to 6cm.

Answer:
C
Step-by-step explanation:
Since the angles in a triangle add to 180 degrees, the third angle is 180-70-45=65 degrees
consecutive integers have a difference of 1 between them
let the brothers have ages n , n + 1 and n + 2 thus
n + n + 1 + n + 2 = 96
3n + 3 = 96
subtract 3 from both sides of the equation
3n = 96 - 3 = 93
divide both sides by 3
n = 
= 31
The ages are 31 , 32 and 33
