Answer:
<u>0.5</u>
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
1
2
= 0.5
θ =
arctan( ΔY ) + 180°
ΔX
= 206.56505117708°
ΔX = 0 – 2 = -2
ΔY = 0 – 1 = -1
Distance (d) = √ΔX2 + ΔY2 = √5 = 2.2360679774998
Equation of the line:
y = 0.5x
When x=0, y = 0
When y=0, x = -0

If you look at the attached graphic, you will see that the altitude (or height) of an equilateral triangle is:
Height = side length * sq root (3) / 2
Area = side^2 * sq root (3) / 4
The answer will be around 145
Answer:
?=7
Step-by-step explanation:
Here is a cool trick that I believe only works with 9.
Add the numbers, 3+9+9+8+x= divisible by 9.
3+9+9+7+8 is 36 which is the only number divisible by 9.
