Answer:
82
Step-by-step explanation:
triangle adds upto 180 degrees
180 - (53+45) = 98
Then two lines adapt to 180 degrees
therefore, 180 -98 = 82
We know, C = 2πr
So, 34.5 = 2 * 3.14 * r
r = 34.5 / 6.28
r = 5.49 m
In short, Your Answer would be 5.49 m
Hope this helps!
X⁴ - 81 = x⁴ - 9² (Difference of 2 squares, then we an write it:
(x²-3)(x²+3) =0, → then (x²-3) = 0 and (x²+3)=0
(x²-3) = 0 → x² = 3 → x = +√3 and x = -√3
(x²+3) =0 → x² = -3 → x = +√-3 and x = -√3→ or i√3 AND x = -i√3
A{ -3 , +3 , -i√3 , i√3}
Answer:
4x+5x=90
9x=90
x=90/9
x=10
4x=40
5x=50
hence the angles are 40 degree and 50 degree respectively.
Hope this may help you
Thank you
