or to be exact : 70.7873
Step-by-step explanation:
In right angle triangles, trigonometry functions can be used
here tan out of sin, cos ,tan seems the most appropriate
tan(x) = opposite/adjacent
tan(x) = 6.6/2.3
x = tan^-1 (6.6/2.3)
x = 70.7873
3⁻¹ is <u>greater than </u>1/4
<u>Step-by-step explanation:</u>
3⁻¹ is nothing but the inverse of 3 .
So it can be written as 1/3.
Value of 1/3 can be found by dividing 1 by 3 to be 0.333...
Value of 1/4 can be found by dividing 1 by 4 to be 0.25
So 0.333 > 0.25
1/3 > 1/4
∴ 3⁻¹ > 1/4
