Can someone please help me with number 30?

1 answer:

5 0

This is an application of the pythagorean theorem.
c^2 = h^2 + b^2
c = 190
b = 102.5
h = ???

190^2 = h^2 + 102.5^2
16100 = h^2 + 10506.25
36100 - 10506.25 = h^2
25593.75 = h^2
sqrt(25593.75) = h
159.98 = h

Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

(8sqrt(3))^2 + b^2 = 16^2

64 * 3 + b^2 = 256

192 + b^2 = 256

b^2 = 64

b = 8

The ratio of the lengths of the sides of this triangle is

8 : 8sqrt(3) : 16

which reduces to

1 : sqrt(3) : 2

This is the ratio of the lengths of the sides of a 30-60-90 triangle.

Use the points (0, 4) and (-2, 3) to find the slope of the line and give the equation of this line.

Sauron [17]

Answer:

Choice C: $m=\frac{1}{2}; y=\frac{1}{2} x+4$

Step-by-step explanation:

To find your slope do:

$\frac{y^2-y^1}{x^2-x^1}$

$\frac{3-4}{-2-0}=\frac{-1}{-2} =\frac{1}{2}$

that's how you get 1/2

4 is just the y-int.
