Using relations in a right triangle, it is found that the values of the variables in the triangle below are given by:

x = 18, y = 6\sqrt{3}

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

  • The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
  • The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
  • The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

In this problem, the hypotenuse is of 12\sqrt{3}, while the opposite angle to side y is of 30º, hence:

\sin{30^\circ} = \frac{y}{12\sqrt{3}}

\frac{1}{2} = \frac{y}{12\sqrt{3}}

y = 6\sqrt{3}

The adjacent side to the angle of 30º is of x, hence:

\cos{30^\circ} = \frac{x}{12\sqrt{3}}

\frac{\sqrt{3}}{2} = \frac{x}{12\sqrt{3}}

2x = 36

x = 18

Help me please! Ray BD is the angle bisector.What is the value of x?
Montano1993 [528]

Answer:

x = 4

Step-by-step explanation:

An angle bisector divides an angle into two equal parts.  This means that you can set the two parts equal to each other and solve for x.

8x + 35 = 11x + 23

(8x + 35) - 35 = (11x + 23) - 35

8x = 11x - 12

8x - 11 x = (11x - 12) - 11x

-3x = -12

(-3x)/-3 = -12/-3

x = 4

A four side sandbox has exactly two right angles, two side leghts 5 ft, and two side leghts 6 ft. What geometric shape best desc
serious [3.7K]

Answer:

Square

Step-by-step explanation:

If its 4 sided and two measures are 90 degrees then that means the other two must be 90 degrees. That means its a square or a rectangle. Now since the 4 sides arent all the same and two sides being 6 and two sides being 5, you can rule out it being a square.

Gus spends 12% of his monthly income on entertainment. He constructs a circle graph to illustrate his budget. What is the degree
Lapatulllka [165]

Answer:

43.2°

Step-by-step explanation:

Just multiply .12 by 360° (the number of degrees in a circle), this will give you the central angle.

Multiplying the decimal means your finding 12.% of 360°

So the angle is 43.2° degrees

At the school election there were three candidates. Isabella got 40 votes, Amelia got 60 votes and Mason got ⅓ of the votes. How
notsponge [240]

Answer: 150 people voted in the election.

Step-by-step explanation:

Let x = Total number of votes.

Mason got \dfrac{x}{3} votes.

Isabella got 40 votes, Amelia got 60 votes.

Then,

Combined votes = 40+60+\dfrac{x}{3}=x

100=x-\dfrac{x}{3}\\\\100=\dfrac23x\\\\ x=100\times\dfrac32\\\\ x=50\times3\\\\ x=150

Hence, 150 people voted in the election.
