Arctan (√3 /3) = 30°. = π/6 rad
That is the value searched, in degrees and radians.
You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3
Answer: #2
Step-by-step explanation:
The answer isnt on there? unless it's A
Rise Over Run
From Yint you go up two and left two making your answer 2 over -2 but that would just be -1 making your answer y=-x
Answer:
1 and 5
Step-by-step explanation:
Lets x and y be those numbers, and lets x be 1 more greater then 4 times y. Then we have:
X=1+4y
The sum of the numbers is 6, so
X+y=6
Put first equation in 2nd for x we get:
1+4y+y=6
1+5y=6
5y=5
Y=1+4*1=5
Then x=1+4*1=1+4=5
