Add 3x to both sides
-3x+10=3x-8
+3x +3x
10=6x-8
+ 8 +8
18=6x
/ / (divide)
6. 6
3=x
It’s 5/7 5/8 I did the math
Answer:
BD = 12 :)
Step-by-step explanation:
Alright, we'll need the Pythagorean theorem for this!
So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)
DC = 5
We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:
BD^2 + DC^2 = BC^2
BD^2 + 5^2 = 13^2
BD^2 + 25 = 169
BD^2 = 169 - 25 = 144
BD = √144 = 12 :)
76 divided by 4 is 19. Add a zero and the answer is 190.
Hope this helps you !!
