Use pythagoras theorem. square root of 13 the answer is b. h^2=3^2+2^2=13
h=
.
Step-by-step explanation:
Your answer would be 7.94 units.
First we must note that a perpendicular bisector halves the side it is bisecting, so FA = FB. This then allows us to say that FA = 9, as 18 ÷ 2 = 9.
Now that we know FA = 90, we can see the right triangle with a hypotenuse AD, which is 12, and a leg FA, which is 9.
This then allows us to use Pythagoras's Theorem to find a leg of a right triangle, c² - b² = a², so we can do:
12² - 9² = 144 - 81 = 63
√63 = 7.93725, which is 7.94 to the nearest hundredth.
I hope this helps!
You can only solve the first one so...
#1 is 4e+6f-14g
A: b + 9
Step-by-step explanation:
If it's the sum of two numbers it is addition, meaning that you add the number of blue bikes(b) to the number of red bikes(9).
