Help me it’s due at 12 I’ve been doing this for 3 days now
Lemur [1.5K]

Answer:

tan(C) = √3/√2

Step-by-step explanation:

First, using Pythagorean Theorem, find AC.

=> AC = √(3√5)² - (3√3)²

=> AC = √45 - 27

=> AC = √18

=> AC = 3√2

tan C = 3√3/3√2

= √3/√2

Which best explains whether a triangle with side lengths 2in , 5in , 4in. is an acute triangle
lutik1710 [3]
So we know that 3,4 and 5 are pythagorean triplet and these result from a right triangle sides length 
- than 3,4 and 5 mean right triangle so 2,5 and 4 mean acute triangle sure or you can prove it in this way too
- than 3^2 +4^2 =5^2 => a right triangle so than 
2^2 +4^2 < 5^2 => an acute triangle 

hope helped

Write an equation of the line that passes through the given point and is (a) parallel and (b) perpendicular to the given line.
inessss [21]

Answer:

(a). <em>y = 3x - 11 ;</em> (b). <em>y = </em>-\frac{1}{3}<em> x - 1 </em>

Step-by-step explanation:

Parallel lines have the same slopes

Slopes of perpendicular lines are opposite reciprocals.

(3, - 2)

The slope of given line is 3

<em>(a)</em>. Equation of ║ line is

y + 2 = 3(x - 3)

<em>y = 3x - 11</em>

<em>(b).</em> Slope of perpendicular line is -\frac{1}{3}

y + 2 = -\frac{1}{3} (x - 3)

<em>y = </em>-\frac{1}{3}<em> x - 1</em>

I need to find the volume for number 10
kumpel [21]

Using the diagonal dimension and the height we can solve for the diameter of the cylinder using the Pythagorean theorem.


x^2 + 9.5^2 = 19.3^2

x^2 + 90.25 = 372.49

x^2 = 372.49 - 90.25

x^2 = 282.24

x = √282.24

x = 16.8


Now we know the diamteer and height, we can calculate the volume using the formula V = pi * r^2 * h

r = 1/2 the diameter = 16.8/2 = 8.4

using 3.14 for pi

Volume = 3.14 * 8.4^2 * 9.5

V = 3.14 * 70.56 * 9.5

v = 3.14 * 670.32

v = 2104.8 cubic meters
