Short Answer x = 22 or C
The chord running through C is the circle's diameter. The angle opposite that diameter is a right angle. Any point on the circumference of a circle will make a right angle with  the two end points of the diameter except the two end points of the diameter. 

So the fact you should use is that the three angles of the triangle make 180 degrees (all triangles have 180 degrees). 

In this case you know two of the angles 
68o is one of them
90o is the other angle
x makes the third angle of the triangle.

x + 68 + 90 = 180      Combine like terms.
x + 158 = 180            Subtract 158 from both sides.
x = 180 - 158
x = 22 degrees <<<< Answer.

What is the ratio for sine
Sphinxa [80]

Answer:

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Step-by-step explanation:

There is a trigonometric acronym for this which is:

Soh Cah Toa

Soh means that sine is opposite over hypotenuse.

Cah means that cosine is adjacent over hypotenuse.

Toa means that tangent is opposite over adjacent.

Let me actually write these out as fractions:

sine is \frac{\text{opposite}}{\text{hypotenuse}}

cosine is \frac{\text{adjacent}}{\text{hypotenuse}}

tangent is \frac{\text{opposite}}{\text{adjacent}}

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Which of these non-terminating decimals can be converted into a ratinaol number
madreJ [45]

Answer

A. O.8743874374387438743....

Step by step explanation

Let's take a = O.8743874374387438743....

10a = 8.743874374387438743....

Similiarly,

10000a = 8743.874374387438743....

Since four decimal places are repeating.

Now subtract a from 10000a

10000 a - a = 8743.874374387438743....  - O.8743874374387438743....

9999 a = 8743

a = 8743/9999

8743/9999 = O.8743874374387438743....

That's it.

Hope you will understand the concept.

Thank you.
