This is valid through the law of syllogism. If you swap lines 1 and 2, then you'll have this argument:
If I step on a beehive, then I will get stung.
If I get stung by a bee, then it will hurt.
Therefore, if I step on a beehive, then it will hurt
------------------
So it's like connecting a chain together. Point A (stepping on the hive), leads to point B (getting stung), which leads to point C (getting hurt). We can take a shortcut to bypass point B to jump from A to C in one step. Check out the attached image for a visual of what I'm referring to.
To find a perpendicular line, the slope is opposite reciprocal. The slope would be -4x.
Put in point slope form:
y - 7 = -4(x - 2)
y - 7 = -4x + 8
y = -4x + 15
(line perpendicular to given equation and goes through the point)
Hope this helps!! :)
Answer:
Let the two angles be x and 2x
Sum of angles of triangle=180°
60+x+2x=180
3x=180-60
x=120/3
x=40
2x=80
Step-by-step explanation:
40 and 80 are other two angles
R = 25 cm = 0.25 m
α = 2.00 rad /s²
T(heta) = 4 π
ω = T(heta)/ t
ω = α t
α t = 4 π / t
t ² = 2 π
t = √ ( 2π ) = 2.5 s
ω = α t = 2 · 2.5 = 5 rad/s
v = ω r = 5 · 0.25 = 1.25 m/s
(1) a (rad) = ω² r = 25 · 0.25 = 6.25 m/s²
(2) a (rad) = v² / r = ( 1.25 )² / 0.25 = 0.15625 / 0.25 = 6.25 m/s²
