PR=
Help me please thanks so much

Answer 1

Formula: U*V=R*T

3*1=4*x

3=4x

x=3/4

Hope it helps!

Answer 2

`\sf PR =(3)/(4)`

Explanation:

Intersecting chords theorem:

It two chords or secants intersect inside the circle, then the product of the length of the segments of one chord is equal to the product of the lengths of the segments of the other chords.

TP * PR = UP * PV

4 * PR = 3 * 1

`\sf PR = (3)/(4)`
