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:
27y - 6
Step-by-step explanation:
3(9y - 2) Multiply 3 times each term in the parentheses
3 * 9y = 27y
3 * -2 = -6
The answer can be found by squaring 6 which gives you 36 minus 30 because negative 5 times 6 is negative 30 so it would be 36-30-3 which is 3
A refraction cup that is the shape of the semicircle will create a sphere if you put two of them together.
Hope this helps:)
