1)
for a valid triangle two sides added together have to always be larger than the third
(otherwise it turns into a line)
12, 18, 6 would not be a valid triangle, because 12+6<=18
but 12, 18, 14 would be valid, because
12+18>14
12+14>18
18+14>12
2)lets start with an obvious right triangle and have the axis along the y and x axis like
so decide some x like -4 and some y like -3 and keep all other coordinates at 0:
A=(-4,0) B=(0,-3) and C=(0,0)
make it a bit more complicated (less 0s) by some x and y translation like (-2,3)
just add that to every point's coordinates and you get
A=(-6,3), B=(-2,0), C=(-2,3)
Answer:
120 deet above ground level
Step-by-step explanation:
180 - 60 = 120
Answer:
second option is the answer of your question
Answer:
$944
Step-by-step explanation:
<h3>
Interest=principle*rate*time (in years)</h3><h3>
I=prt</h3>
<em>Principle=800</em>
<em>Rate=0.06 (6%)</em>
<em>Time=3</em>
<em>800*0.06*3= 144</em>
Total
Principle+Interest= Total
800+144=944
Answer:
48 ft.
Step-by-step explanation:
Since triangles ABC and DEC are similar (you can prove this quite easily), then we know the ratio of the sides are equal. This is a property of similar triangles. So we take the ratio of the sides CE and DE and the ratios of the sidesBC and AB.
We get:
So x is 48 ft.
