How? in the world do you do this it’s very confusing

This is a 30° - 60° -90° triangle, which means that the sides will measure: 1, √3, 2.

Note that:

2 is the hypotenuse, opposite of the 90° angle

√3 is the longer side, opposite of the 60° angle

1 is the shortest side, opposite of the 30° angle

7 is in the place of 1, and is the shortest length measurement.

x is in the place of 2, which is twice the size of the place value of 1, which is 7

x = 7(2)

x = 14

y is in the place value of √3, which is √3 more than the place value of 1

7 x √3 = 7√3

y = 7√3

x = 14, y = 7√3, or (B), is your answer

hope this helps

1/5^2 = 7.56/45

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
