Answer:

Step-by-step explanation:
We have been given an equation
. We are asked to find the solutions of our given equation.
First of all, we will cross multiply our given equation as:

Subtract
from both sides:


Now we will factor out
.



Now we will factor by splitting the middle term.



Now we will use zero product property and solve for x as:



Now, we will check for extraneous solutions.
We can see that
will make both denominators zero because our function is not defined at
.
Therefore, the solution for our given equation is
.
Let's firstly convert the mixed fraction to "improper" and then proceed,

Answer:40 degrees
Step-by-step explanation:
Since triangle similarity depends on either the measurement of sides which no given about it here or equal angles so angle c = angle R
