9.83
Explanation: 6+8+10+10+12+13 = 59
There are 6 numbers so 59 divided by 6 is equal to 9.833… simplified it would be 9.83
Answer:
Look below
Step-by-step explanation:
Looking at all the images, we can see that the hypotenuse seems to always be the longest side of the triangle.
Make proportions and reduce them.
6/9=2/3
10/15=2/3
The two rectangles are similar proportionally with a ratio of 2:3.
Does that answer your question?
First way
arcsin(1/4) means that 1/4 sin of the angle.
sin(α)=1/4
sin²α+cos²α=1
(1/4)²+cos²α=1
cos²α=1-1/16 =15/16
cosα=+/-(√15)/4
<span>Second way
</span>
sin(α)=1/4 =opposite leg/hipotenuse
cos(α)=adjacent leg/hypothenuse
adjacent leg =√(hypotenuse²- Opposite²)=√(16-1)=√15
cosα=+/-√15/4
For one value of sinα, possible 2 values of cosα.
