In the right angled triangle ACD shown with isosceles triangle ABC and ADC, AB = AC = AD

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

A triangle is a polygon that has three sides and three angles. Types of triangles are<em> isosceles, equilateral and scalene</em>.

In the diagram shown:

AB = AC = AD

What is the volume of a regular hexagonal prism with a side length of 4 and a height of 9? Please give the answer as square root

likoan [24]

The height of an equilateral triangle with side s is s*sqrt(3)/2
The area of an equilateral triangle is therefore s^2*sqrt(3)/4
The area of a hexagon with side s is 6 times the area of an equilateral triangle
=6*s^2*sqrt(3)/4
=3s^2*sqrt(3)/2

Here s=4,
Area of base (hexagon) = 3*4^2*sqrt(3)/2=24sqrt(3)
Volume of prism
=(base area)*height
=24sqrt(3)*9
=216sqrt(3)

5x - 1 - 2x = 20. Solve for x.

Rasek [7]

Answer:

x = 7

Step-by-step explanation:

Given

5x - 1 - 2x = 20, that is

3x - 1 = 20 ( add 1 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Bro can someone please help me on these three questions I’ve been trying to get help on these questions for like the past 30 min

Inessa05 [86]

Answer:

Step-by-step explanation:

1). By applying cosine rule in the given triangle,

cos(x°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(x°) = $\frac{6}{8}$

x = $\text{cos}^{-1}(\frac{3}{4} )$

x = 41.41°

2). By applying cosine rule in the given triangle,

cos(x°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(x°) = $\frac{4}{5}$

x = $\text{cos}^{-1}(0.8)$

x = 36.87°

3). By applying cosine rule in the given triangle,

cos(x°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(x°) = $\frac{51}{85}$

x = $\text{cos}^{-1}(0.6)$

x = 53.13°

Identify the ordered pair that has the same slope as the equation y= -x+3

dybincka [34]

Answer: (1,2) and (-1,4)

Step-by-step explanation:

Slope = $\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

The slope of the line given is - 1

Checking which of the ordered pair has the same slope , the formula will be used to check , and the only pair that will give - 1 is (1,2) and (-1,4)
