Hence, the set of values that holds true is:

2-3-4

Hence, option: D is true.

Step-by-step explanation:

We are asked to find which set of the values make the following inequality:

2x-1<10 true.

i..e we will put the given set of value s in place of xx and check whether the value of 2x-1 is less than 10 or not.

If it is then the set of values hold true.

10-15-20

put x=10

2x-1=2×10-1

=20-1

=19 which is not less than 10.

Hence, option: A is incorrect.

5-7-9

when x=9

2x-1=2×9-1

=18-1

=17 which is not less than 10.

Hence, option: B is incorrect.

4-6-8

when x=8

2x-1=2×8-1

=16-1

=15 which is again not less than 10

Hence, option: C is incorrect.

2-3-4

when x=2

2x-1=2×2-1

=4-1

=3<10

when x=3

2x-1=2×3-1

=6-1

=5 < 10

when x=4

2x-1=2×4-1

=8-1

=7<10

Hence, option: D is true.

Hence, the set of values that holds true is:

2-3-4

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
