Find the value of× to make the following expression true. 6×=216

The value of x for which the expression is true is 36 .

Step-by-step explanation:

Given as :

The linear expression is

6 × x = 216

Now, To make the expression true i.e left hand side equation = right hand side equation

So, LHS = 6 × x

And RHS = 216

i.e here must be some value of x so that LHS = 216

Now

∵ 6 × x = 216

∴  x =

Or x = 36

So, The vale of x must be equal to 36 , so that equation will be true

Prove

LHS = RHS

∵ ,  6 × x = 216

Now, put x = 36

Or,  6 × 36 = 216

i.e 216 = 216

So, The equation is true

Hence, The value of x for which the expression is true is 36 . Answer

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
