2+x=50
That is what I would do. I hope this helps!
Answer:

Step-by-step explanation:
We have to find the quotient of the following division,
.
Now,
=
{Since all the terms in the expression are in product form, so we can treat them separately}
{Since we know the property of exponent as
}
=
=
(Answer)
{Since we know,
}
X = 45.
Since opposite exterior angles are congruent, you can set the 2 values equal to each other. When you solve for x, you should get 45.
is proved
<h3><u>
Solution:</u></h3>
Given that,
------- (1)
First we will simplify the LHS and then compare it with RHS
------ (2)

Substitute this in eqn (2)

On simplification we get,


Cancelling the common terms (sinx + cosx)

We know secant is inverse of cosine

Thus L.H.S = R.H.S
Hence proved
