What is one unexpected problem associated with cell phone use? a. it decreases the efficacy of your peripheral vision. b. it distracts your hearing from events on the roadway. c. it causes you to misjudge distances.

The correct answer is:

Option: A

A. It decreases the efficacy of your peripheral vision.

Step-by-step explanation:

Today the cell phone are likely to become a curse.

Because Now a person is in unhealthy relationship with the phone. They have started isolating themselves from the society. Even while walking on the road they are focused on the cell phones.

So, the unexpected problem that is associated with cell phone use is:

A. It decreases the efficacy of your peripheral vision.

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
