Answer:
yes of course you can make a triangle
We know the area is length * width.
So we know the length is 8 feet.
The width is 7 + x feet.
Multiply them:
8 * 7 + x.
56 + x.
So option D)
sorry, I misread the options! I meant D) not A)
Input a value for x and get a value for y
y=2x-4
x=3
y=2(3)-4
y=6-4
y=2
ycoordinate=2
coordinate=(3,2)
Answer:
it does represent the total area
Step-by-step explanation:
we can change cos to sin by saying cosx=sin(90-x)
now we drop sin and make the angles equal (nothing needs to be added or subtracted since its in the first quadrant)
90-x=20+x+k.360.......kEZ (k is an element of set of integers) (we say k.360 if it's cos and sin and k.180 if it's tan)
-x-x=20-90+k.360........kEZ
-2x=-70+k.360.........kEZ
divide all terms by -2
x=35-k.180.......kEZ
