The equation tan-1(8.5/7.7) = x can be used to find the measure of angle lkj

Given equation :

We know the formula,

can be written as

In the given problem angle theta is taken by x and fraction a/b is taken by 8.5/7.7.

In order to find the value of tan^-1(8.5/7.7), we need to put arc tan or tan^-1(8.5/7.7) in calculator.

By default, calculator would give angle in radians.

Also if you want answer in degrees, please do not forget to change the radian key(button) into degrees.

On putting  tan^-1(8.5/7.7) in calculator, we get 0.834741.. radian approximately.

And in degrees it would be 47.827 degrees approximately.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
