51. Find The Length Of The Unknown Side X Of This Triangle, Evaluate Your Answer To Two Decimal Places.

Answers

Answer 1

Answer:

See work, below.

Step-by-step explanation:

The radius of this circle is 10 and so the diameter is 20.  The measure of the angle opposite side x is found as follows:

                      adj side

 cos theta = ------------------- = 18/20.  Find theta:

                      hypotenuse

theta = arccos 18/20 = 0.451 radian.

Now use the sine function to find x:

                                          x                       x

sin 0.451 radian      = ------------------- = ------------- = 0.651

                                    hypotenuse          20

which results in x = 20(0.651) = 13.02

x = 13.02 units

I should have used the Pythagorean Theorem up front.

18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72

Step-by-step explanation:

Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Answers

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55


Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.

the answer is C) 122.4
Answer:
The area of the triangular case = 61.2 square inches
Step-by-step explanation:
P.S - The exact question is -
Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.
To find - What is the area of the triangular case ?
Proof -
Given that,
Base of triangle = 14 2/5 in
Height of triangle = 8.5 in
We know that,
Area of triangle =1/2 *base *height =1/2 *8.5 *14 2/5
=1/2 * 8.5 * 14.4
=1/2 * 122.4
=61.2

we get
The area of the triangular case = 61.2 square inches

Benjamin believes that 1/2 % is equivalent to 50%. Is he correct? Why or why not? Please explain.

Answers

Answer:

Benjamin is correct.

Step-by-step explanation:

1/2 converted to a decimal (1 divided by 2) is 0.50, which when converted to a percentage is 50%.

1 ÷ 2 = 0.5

.5 × 100 = 50 ⇒ 50%

So, 1/2% = 50%

Also, 1/2 is 50%. So, that should automatically prove that he is correct.

Suki’s method is definitely the better choice. It was randomly selected and includes a greater amount of students. Dinah’s method has a little more bias.
