I've gotten the answer to this I just need to know how to get the answer (the answer is 208.5) please help me its due Monday

With shapes like these, you need to split it into parts you can find the area for and add it together at the end.

Let's take the rectangle out of the two other triangles first,

15x8=120. First area solved.

Now remember, you find areas of triangles by bxh/2. Let's do the one on the side first. 9x8=72. 72/2=36. Second area solved.

The final triangle has a height of 7 m, and it's parallel to the 15 m length from before. 7x15=105, 105/2=52.5. Last area found.

Now let's add them all together. (120+36+52.5)=208.5.

Hope this helped!

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

yes. we do proportions in probabilities.
