Answer:
The value of x = 13.5.
Step-by-step explanation:
<u>In this question x is missing.</u>
<u>So, the question would be:</u>
<u>tan 34° = x/20.</u>
Now, to find the value of :
Multiplying both sides by 20 we get:
On simplifying both sides we get:
So, to get the value of to nearest tenth is 13.5. As we see in hundredth place it is 9 and 4 in tenth place, so after rounding to tenth place 4 will change to 5 so the value is 13.5.
Therefore, the value of x = 13.5.
Answer: First option.
Step-by-step explanation:
You can idenfity in the figure that is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:
Knowing this, you can set up the following equation:
Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle .
This is:
