65 degrees

Step-by-step explanation:

Option B is correct 65°

Step-by-step explanation:

Apply the trigonometric identity sine

Do not forget to convert your calculator into degree form if it is set to radian.

Alright since you haven't studied trigonometry forget what i said here xD

The table given are the ratios of the respective angles 55, 65, 75.

First we need the adjacent side of the triangle. We have the opposite side of the triangle which is 6.1 and the hypotenuse which is 6.7 we use Pythagoras theorem

So now lets compare the ratios in table

Firstly

so we can see that all these values 0.413, 0.91, 2.2 correspond to the angle 65° so Option B is correct

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
