Area of a triangle = 1/2 ab sinC
In this equation the angle C is between the two adjacent sides ab
Since the lengths are equal we can call them both X
Hence 254= 1/2 (x)(x) sin53
By simplifying 508 = (x^2) sin53
So therefore x is the square root of 508 divided by sin53 which means the length of the sides is 35.8km to 3 significant figures
It is going to 21 because when you is divid 386÷18=21and you don't have 21 up there either I did it wrong or you do not have up there bc you missed up
Answer:
2 Questions.
Step-by-step explanation:
To calculate a how much a percentage is of a number, you multiply the number by the percent.
