Consider right triangles ADB and ADC in the figure, right angle D.

By alternate transversals ABD=63° and ACD=11°.

\tan 63 = \dfrac 8 y

\tan 11 = \dfrac 8{x+y}

y = \dfrac{8}{\tan 63}

x = -y +  \dfrac{8}{\tan 11}

x = \dfrac{8}{\tan 11} -  \dfrac{8}{\tan 63}

x \approx 37.08 \textrm{ meters}

That's in one second, so

Answer: 37 meters per second

The distance between the points (12,9) and (0,4) is A) 14 units B) 13 units C) 15 units D) 16 units
Juliette [100K]

Answer:

Option B  13 units is correct.

Step-by-step explanation:

The formula used to find distance between 2 points is:

d(P1,P2)=\sqrt{(x_{2} -x_{1})^2 + (y_{2} -y_{1})^2 }

x₁ = 12 x₂ = 0 y₁= 9 and y₂=4

Putting values in the formula:

=\sqrt{(0-12)^2+(4-9)^2}\\=\sqrt{(-12)^2+(-5)^2}\\=\sqrt{144+25} \\=\sqrt{169} \\=13

So, Option B 13 units is correct.
