A certain television is advised as a 37-inch tv (the diagonal length).if the width of the tv is 12 inches, how many inches tall is the tv

The TV is 35 inches tall
Step-by-step explanation:
Diagonal(D) is 37 inches, height (H) is X inches s,Width(W) is 12 inches
D^2 = H^2 + W^2
37^2 = X^2 + 12^2
(HEIGHT) X ^2 =37^2-12^2
(HEIGHT)X ^2=1369-144
(HEIGHT) X ^2=1225
(HEIGHT)X=35
So the TV is 35 inches tall

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
