Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD = 4
Vinil7 [7]

Answer:

BD = 6

Step-by-step explanation:

Theorem:  The altitude to the hypotenuse of a right triangle is the mean proportional between the segments of the hypotenuse.

So, \frac{4}{BD} = \frac{BD}{9}

BD^{2}  = 36

BD = 6

See how easy that is IF you know the theorem.

HELP PLEASE THANK U
Solnce55 [7]
This is just my guess but I want to say no they are not similar because the first 10 + 5 = 15
8 + 5 = 13 not 12
To make it similar, 8 needs to be 7. This is ONLY my guess, I’m not 100% confident in my answer

Given AC with A(3, 4) and C(-9, -2), if B
babymother [125]

Answer:

B = (- 4, \frac{1}{2} )

Step-by-step explanation:

Using the Section formula

x_{B} = \frac{7(-9)+5(3)}{7+5} = \frac{-63+15}{12} = \frac{-48}{12} = - 4

y_{B} = \frac{7(-2)+5(4)}{7+5} = \frac{-14+20}{12} = \frac{6}{12} = \frac{1}{2}

Thus coordinates of B = (- 4, \frac{1}{2} )
