What value of x satisfies

LenaWriter [7]

Answer:

See explanation

Step-by-step explanation:

The given trigonometric equation is $cos(90-x)=-\frac{\sqrt{3} }{3}$ .

We take the inverse cosine of both sides to get:

$90-x=cos^{-1}(-\frac{\sqrt{3} }{3})$

$90-x=125$

$x=125-90$

$x=-35\degree=325\degree$ to the nearest degree

None of the options satisfies the given equation.

But if the question is actually;

$cos(90-x)=-\frac{\sqrt{3} }{2}$

Then;

$90-x=\cos^{-1}(-\frac{\sqrt{3} }{2})$ .

$90-x=210$ .

$90-x=210$ .

$x=-120\degree$ .

Or

$x=360-120=240\degree$ .

In this case the answer will be B

Answer:

x = 2

Step-by-step explanation:

2 log₅ x = log₅ 4
2 log₅ x = log₅ 2²
2 log₅ x = 2 log₅ 2
log₅ x = log₅ 2
x = 2
