Answer:
put it in the catrulater
Step-by-step explanation:
Begin solving like you normally would. Add 2.25 to both sides and subtract 9x from both sides to try getting all x values on one side. However, you will find that after subtracting 9x from both sides, all x values go away, and you end with -2.25=1.6. This is not true (-2.25 is not 1.6), so the answer is no solution. There is no value of x which satisfies that equation.
ANSWER

EXPLANATION
Recall that,

That is why

is equivalent to

This implies that,

This is the same as,

When we are dividing by

we move the decimal point backwards two times.
This implies that,
Answer:
We have that 
Step-by-step explanation:
We have just to replace n=10 on the general equation

Therefore:

ASA, SAS, AAS,
if LA stands for leg-angle then you could do that too
