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
A = 28.356 ≈ 28.4
Here, we use law of sines, which says that sina / A = sinb / B. We know that b = 130 degrees, B = 10cm, and A = 6.2cm. Using algebra, we solve sina / 6.2 = sin130 / 10 to get a final answer.
The angle would be 70 degrees because 180-110=70
Answer:
Easy -2x
Step-by-step explanation:Because both a positive y and a negative y cancle out eachother so all thats left is both of the negative x's
