Exercise 33 Page 739

Recall that in a circle two minor arcs are congruent if and only if their corresponding chords are congruent.

x=5

Practice makes perfect

Let's look at the given diagram.

Recall that in a circle two minor arcs are congruent if and only if their corresponding chords are congruent. Since WTY≅TWY, the chords TY and WY are congruent. TY = WY 4x=2x+10 Let's solve the above equation using inverse operations.

4x=2x+10

LHS-2x=RHS-2x

2x=10

.LHS /2.=.RHS /2.

x=5

The value of x is 5.
