I have never been so confused in my life... if someone could explain how to do this I’d appreciate it.

  x = 143°

Step-by-step explanation:

When chords cross, the angle between them is the average of the measures of the intercepted arcs. Here, it is useful to consider the larger angle where the chords cross, the supplement of 37°, which is 143°. That is the average of the two arc measures (x+5) and (x-5). That average is ...

  ((x +5) +(x -5))/2 = 2x/2 = x

In short, x = 143°.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
