Since the symbol tells us the angle is 90 degrees we know the 4x and 5x add up to make 90 degrees.
Lets use this to make and form an equation
5x + 4x = 90
9x =90 (collect the x values)
x = 10 (divide both sides 9 to find what x is)
Here is you're answer:
In order to find the answer you have to switch all the options into decimals to see which one is equivalent to 2.46!
Therefore you're answer is option C "2 23/50." Remember when wanting to find the decimal divide the numerator by the denominator after you convert the mixed number (if it's a mixed number) into a improper fraction!
Hope this helps!
36/35 or 1 1/35. Change the denominators to a common one of 35, which in order to get an equivalent fraction, you change it to 21/35 and 15/35.
