Does anyone know this?

Option (C)  1.88*10⁻⁵>6.59*10⁻⁶

Step-by-step explanation:

 1.88*10⁻⁵>6.59*10⁻⁶

On solving the equation C)

The values are 0.0000188>0.00000659 which is correct as compared to other options as the equation C is true

Whereas in option B, the solved values are 0.000006590.0000188 which is not true

In option D) 0.0000188 < 0.00000659 which is opposite of option C) and is false. Option A is also not true as the LHS And RHS values are not equal on solving the given value.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
