SinB = cosC = AC / BC = 8/10 = 4/5;
tgB = ctg C = AC/AB = 8/6 = 4/3, because we use T. Pitagora for calculating AB;
sinC = cosB = AB/ BC = 6/10 = 3/5;
tgC = ctgB = AB/ AC = 6/8 = 3/4.
Answer:rrrrrrrrrrrrrrrrrrrrrr
Step-by-step explanation:
yhrrrrrrrrrrrrrrrrrrrrrrrrrr
Just got it The answer is C 3.
X=3. 33x-21x equals 12x. 24+12=36. 12x divided by 36 equals 3
