We grapht hem
we see that the base is from (-2,2) and (6,2), 8 units long
the height will be from y=2 to y=8 or 6 units
so then, the area=1/2 times base times height=1/2 times 8 times 6=24 square units
One fifth is the same as

and 15 is the same as

So just times across,

×

Resulting in(1 x 15= 15, and 5 x 1= 5),

If you need/want to reduce it, divide both numbers by 5. Leaving you with the simplified answer of

or 3. Either answer works. :)

-2.5 because a positives opposite is a negative.
Answer:
To know what the ratio for the cos of theta, we actually have to see the adjacent and hypotenuse values. cos=adjacent/hypotenuse.
Step-by-step explanation:
75+37=112. 180-112=68. 68-7=61. 61/5=12.2. so x=12.2
