Find the value of x.
answer options: 17, 7, 14, 10

7

Step-by-step explanation:

Since both chords are congruent and the distance of the x and 7 are equidistant from the center, then the value of x will also be 7.

Left side chord will have a value of y + 10

The right side chord will have a value of y + 10

Now since the right angles on both sides are equal, then x = 7.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
