Consider the 30°-60° right triangle shown whose hypotenuse is equal to one. Clearly this triangle is half of an equilateral tria
Bad White [126]

Answer:

Step-by-step explanation:

Given triangle ABC is a right triangle.

m∠ACB = 60°

m∠CAB = 30°

m(AC) = 1 unit

A). Shorter side of the given triangle = Side BC

By applying cosine rule,

cos(∠C) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

cos(60°) = \frac{BC}{AC}

BC = \frac{1}{2}(AC)

BC = \frac{1}{2}

Length of the shorter side = 0.5 units

B). Longer side of the given triangle = side AB

By applying Pythagoras theorem in the given triangle,

AC² = AB² + BC²

1² = AB² + (\frac{1}{2})^2

1 = AB² + \frac{1}{4}

AB = \sqrt{1-\frac{1}{4}}

AB = \sqrt{\frac{3}{4}}

AB = \frac{\sqrt{3} }{2}

Length of the longer side = \frac{\sqrt{3}}{2}

The net of a rectangular prism is shown below. The surface area of each face is labeled. Which values represent the dimensions i
Naddika [18.5K]

Answer:

<h2>The dimensions are 3, 4 and 6 centimeters.</h2>

Step-by-step explanation:

Notice that the surface of 24 square centimeters is formed by 6 times 4, which gives 24 square centimeters.

The 12 square centimeres surface is formed by 3 times 4, which gives 12.

The 18 square centimeters surface is formed by 3 times 6, which gives 18.

Therefore, the three dimensiosn to form the prism are 3 cm x 4 cm x 6 cm.

Where 6 cm is the height, 3 cm and 4 cm are the width and length.

Solve the equation for y.
gayaneshka [121]

Answer: C

Step-by-step explanation:

2x+5y=5

\mathrm{Subtract\:}2x\mathrm{\:from\:both\:sides}

2x+5y-2x=5-2x

\mathrm{Simplify}

5y=5-2x

\mathrm{Divide\:both\:sides\:by\:}5

\frac{5y}{5}=\frac{5}{5}-\frac{2x}{5}

\mathrm{Simplify}

\bf{y=-\frac{2}{5}x  + 1}

How do you solve for the y-intercept? Show steps please
Marianna [84]

Step-by-step explanation: The y-intercept is where the line on a graph crosses the y-axis. For example Y=2x-2. The line crosses the y-axis at (0,-2). So the Y-intercept would be (0,-2)

When we look at Y=mx+b (slope intercept form)

M being the slope and B being the Y intercept.

So to write it as an ordered pair you just need to put 0 in place of the x-coordinate. So (0,-2)
