First, find the missing leg of ΔBCD (line BD). Using the Pythagorean Theorem, subtract (5^2)-(3^2) [25-9], and you get 16. Find the square root of 16, and you get <em>4</em> for line BD. Now, you can find AB. Add (7^2)+(4^2) [49+16], and you get 65. Now, since 65 isn't a perfect root, just use √(65)
Answer: Line AB equals √(65).
Answer:
Ok so im not the best at explaining but its worth a shot
C)25
Step-by-step explanation:
we already know that the formula to find area is
A=l*w
and that every square is 1 square unit.
So in the first part on the far left, you count down 8 and over 2 to find how many total squares are shaded. This is the length and width of that one part so you multiply 8*2 to get 16.
In the next part, you should count starting at -1 over to 5 to get 6. It only has a width of 1 so 6*1 is still 6.
In the last part you start counting at -3 and count down to -6 and this gives you 3. It is 1 unit wide so 3*1 is 3.
Add 16+6+3 together because that is the combined area of the 3 parts and we get 25
Like i said im definitely, by no means, the best at explaining but if this helped even a little that's awesome, if you have any particular questions i can try to answer them in the comments
Answer:
11n
Step-by-step explanation:
The expression is 7n + 4n. Since 7n and 4n are like terms (they both are variables with n), we can combine them so the expression becomes 7n + 4n = 11n.
Answer:
109.899098772yd
Step-by-step explanation:
90-16=74
cos(74)=x/640
I think 55 because you would multiply 11×5
