Answer with Step-by-step explanation:
We know that
sinФ=Perpendicular/hypotenuse and cosФ=Base/hypotenuse
Now, we have to calculate the value of sin A and cos A
As we can see from the graph Perpendicular=8
Base=6
and Hypotenuse=10
Hence, sin A=8/10=0.8
and cos A=6/10=0.6
Hence, exact value of sin A=0.8 and exact value of cos A=0.6

Answer:
See below.
Step-by-step explanation:
If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula.
If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:
Example:
Find the area of the composite figure by splitting the figure into two shapes - two rectangles.
One rectangle is 2 x 9 = 18.
The other rectangle is 2 x 4 = 8.
Together the area is 18 + 8 = 26.
