coordinate of B= (2+3,0) = (5,0)

by pythagoras' theorem,

height of triangle^2 + half length of AB^2 = AC^2

height of triangle^2 = 3^2-1.5^2

height of triangle ^2= 6.75

height of triangle= √6.75

coordinates of C= (1.5,√6.75)

Answer:

B: (5,0)

C: (3.5 , 3√3/2)

Step-by-step explanation:

ΔABC: equilateral triangle CA=AB=BC=3

B: (2+3,0) i.e. (5,0)

AD=3/2=1.5

CD²=CA²-AD2 = 9 - 9/4 = 27/4 CD = 3√3 / 2

C: (2 + 3/2, 0 + 3√3/2) i.e. (3.5 , 3√3/2)

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>P(t) = Po(1 - r)^t

P(t) = price after t months --> S
Po = initial price -- P
r = rate as a decimal

S = P(.9)^4
-> = 100(.9)^4
-> = 65.61

(100 - 65.61)/100

The gable end of the roof shown is divided in half by a vertical brace. Find the distance h (in ft) from an eave to the peak. 41

nlexa [21]

Answer:

h = 9 ft

Step-by-step explanation:

Assume the diagram is like the one below.

∆ABD is a right triangle.

We can use Pythagoras' Theorem to find the height h.

$\begin{array}{rcl}h^{2} + 40^{2} & = & 41^{2}\\h^{2} + 1600 & = & 1681\\h^{2} & = & 1681 - 1600\\& = &81\\h& = & \sqrt{81}\\&=& \mathbf{9}\end{array}\\\text{The height of the gable is $\large \boxed{\textbf{9 ft}}$}$
