First you multiply the numerator and denominator. So 1 times 2 is 2. And 8 times 5 is 40 and then you simply it is 1/20 because 2 divide 2 is 1 and 40 divide 2 is 20 so it is 1/20.

1/8 plus 2/5=you dot know yet so let me explain to you ok alright 5 can not go into 8 and 8 can not go into 5 so what you need to do is make the denominator 8 times 5 which equals 40. 40 will be both of the denominators then you will do 8 times 2 equal 16 then you will do 5 times 1 which equal5.1/8 is now5/40and2/5 is now 16/40 then you will multiply but when you fro keep the 40 and multiply the numerator .You may have to simplify.

Identify sinJ as a fraction and as a decimal rounded to the nearest hundredth.

KiRa [710]

In the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.

In trigonometry, for a right triangle, the sine (sin) of any angle θ is given as the ratio of its opposite side to the hypotenuse of the triangle, that is, sin θ = (opposite side)/(hypotenuse).

In the question, we are asked to find the trigonometric ratio, sin J, for the given right triangle JKL.

The side opposite to angle J is KL, which has a value of 3 units.

The hypotenuse of the given right triangle is JK, which has a value of 7.8 units.

Thus, sin J can be calculated as:

sin J = KL/JK = 3/7.8 = 5/13 = 0.39.

Thus, in the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.
