Answer:
Option C.
Step-by-step explanation:
we know that
If two figures are similar, then the ratios of its corresponding sides is equal and its corresponding angles are congruent
so
m<A=m<J
m<B=m<K
m<C=m<L
therefore
The measure of angle J is the same that the measure of angle A
The answer is C that is X=7 and X=-1
multiple x through the given equation to get rid of a fraction. It will be
After that bring 6X to the LHS of the equation
so that it will look like the general equation that is
Use the quadratic formula (or any other approach to find the values of x
You will arrive at
