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:
<u>B. 2</u>
To find MAD, find the mean of the set, then find how far each number is from the mean. Next, find the mean of THAT set of numbers. Yea, I know it's a bit confusing... don't worry!
Find the mean of the set:
12 + 10 + 10 + 8 + 6 + 7 + 7 + 12
72
72 / 8
<u>9</u>
Find how far each number is from 9:
12 - 9 = <u>3</u>
10 - 9 = <u>1</u>
10 - 9 = <u>1</u>
9 - 8 = <u>1</u>
9 - 6 = <u>3</u>
9 - 7 = <u>2</u>
9 - 7 = <u>2</u>
12 - 9 = <u>3</u>
Find the mean of that number set:
{3, 1, 1, 1, 3, 2, 2, 3}
3 + 1 + 1 + 1 + 3 + 2 + 2 + 3
16
16 / 8
<u>2</u>
<u>So the answer is 2!</u>
Not so hard after all :D
Answer: The Answer To Your Question Is 25n
Step-by-step explanation: 5(2+3n)
1. Do the Parenthesis: (2+3n)= 5n
2. Multiply: 5 times 5n= 25n
HOPE I WAS HELPFUL I KNOW THE ANSWER IS RIGHT......
Hello!
First you have to find BO
BC = 27
AO = CO
CO = 24
BO = 27 + 24
BO = 51
Now we use the Pythagorean Theorem
24^2 + b^2 = 51^2
Square the numbers
576 + b^2 = 2601
Subtract 576 from both sides
b^2 = 2025
Take the square root
b = 45
The answer is A) 45
Hope this helps!
