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:
9/2 or 4 1/2
Step-by-step explanation:
- 3/4 ÷ 1/6 = 3/4 × 6
- 3/4 × 6 = 18/4
- 18/4 = 9/2
- 9/2 = 4 1/2
Therefore, the answer is 9/2 or 4 1/2.
Answer:
b
Step-by-step explanation:
I just did it in my math class and got it right
-10 is equal to 5 subtracted from a number
Assume that the number is x
So the equation will be
we put x at first because in subtraction the number after the word "from" comes first
Now let us find x
We need to move 5 to the left side to find x, so add 5 to both sides
The number is
B.) 18x^3
Multiply
6 * 3 = 18
When multiplying exponents, you always add.
x^2 * x = x^3
Combine
18x^3
