Answer:
A (I believe)
Step-by-step explanation:
since the part with the triangle is 6 yards, and it looks about half of that whole side, I'm going to assume that that side is 12 yards, and since it's a square each side will be the same length. so multiply 12 and 12 to get 144.
Now divide that by four so you can get the area of a fourth of the square and find the area of the triangle. 144 ÷ 4 = 36
Now divide 36 by 2 to get the area of the little triangle. 36 ÷ 2 = 18
Now divide 18 by 6 to get x. 18 ÷ 6 = 3
In conclusion, the answer should be A.
Hope this helped!!! :3
5 years because when you divide 90 by 18 to get how many years it takes the tree to grow to 90 inches tall, you get 5.
If you're taking trig, the "sum and difference formulas for trig functions" are basic facts that you'll need to learn and commit to memory. I'd suggest you look up these formulas on the net. You will likely immediately find listings for the sine, cosine and tangent.
Answer:
53 degrees
angle DCE is congruent to angle DAE.
for the triangle...
b=2h
a=(1\2).bh=648
(1/2).2h.h=648
h2=648
h-18|2 in
h=36|2 in
for the rectangle...
L=3+w
a=l+w=648
{3+w}w=648
w2+3w-648=0
Only positive W values make sense here..
w-24=0
w=24 in
So..
L=3+24
