Step-by-step explanation:
Answer:
sin A = 12 /13
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin A = opp / hyp
sin A = 12 /13

Hence,

is cutting each other in this equation.
So,

can be of any value.i.e.,infinite.

<u>Answer:
</u>
The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.
<u>
Solution:
</u>
Given that current population of city is 27900.
Also, population of a city has decreased by 38% since it was last measured.
Let assume that population of city when it was last measured = x
Decreased of 38% means x-38% of x . we can write this as,



So current population is 
Equating above expression to the given value of current population, we get


x=45000
Hence previous population of city was 45000.
