Answer:
π4;3π4
Step-by-step explanation: Trig table gives:
sinx=√22 --> arc x=π4
Unit circle gives another arc x that has the same sin value:
x=π−π4=3π4
Extraneous Solutions maybe?
Answer:
First answer is 14
Second answer is 25
Step-by-step explanation:
Median is the middle ( 1 2 3 4 5 the median would be 3)
You start at 2 and end at 27
List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)
In this case there are two 14 & 15
14+15=29 29÷2=14.5
Since there are no decimal answers you are left with 14
Range you take the two end numbers and subtract them (27 & 2)
27-2=25
Hopefully this helps!
Answer:

Step-by-step explanation:
A right angled triangle is given to us and we would like to find out the value of sin(A) .
From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

On using sin both sides ,

As we know that the value of sin30° = 1/2. So;

Simplify by converting it into decimal ,

<u>Hence</u><u> </u><u>option</u><u> </u><u>B</u><u> </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u>
And we are done!
