Answer:
Step-by-step explanation:
You have an angle bisector in AD. That means the sides are in proportion to to BD and DC
It's much easier just to look at the proportion.
AB / BD = AC/DC
18 / (3x - 3) = 15/(x + 5) Cross multiply
18*(x + 5) = 15 (3x - 3) Remove the brackets
18x + 90 = 45x - 45 Switch the sides.
45x - 45 = 18x + 90 Subtract 18x from both sides
<u>-18x -18x</u>
27x - 45 = 90 Add 45 to both sides
<u> +45 45</u>
27x = 135
x = 5
But that's not the answer (even though it is correct). You want BD
BD = 3x - 3
BD = 3*5 - 3
BD = 15 - 3
BD = 12
Answer:
7° F
Step-by-step explanation:
I just guessed lol uhm yeah
168 is twice 84, whereas 84 is the square of 7*12. Therefore,
168 = 2(84) = 2(2)(42), or 2(2)(2)(3)(7)
The prime factors of 168 are 2^3*3*7.
