In the diagram, PN¯¯¯¯¯ is the perpendicular bisector of AB¯¯¯¯¯ and is also the angle bisector of ∠CPD. If m∠CPD = x, which qua

zaharov [31]

Since ∠CPD = x and segment PN is the angle bisector of this angle, therefore segment PN equally divides ∠CPD into two angles. Which means that:

∠CPN = ∠NPD = x / 2

Further, segment PN is also the perpendicular bisector of AB which further means that the intersection formed by PN and AB creates a right angle (90°). Therefore:

∠NPD + ∠DPB = 90°

x/2 + ∠DPB = 90°

∠DPB = 90 – x/2

Therefore:

sin∠DPB = sin(90 – x/2) which is not in the choices

However we know that the relationship of sin and cos is:

sin(π/2 - θ) = cos θ

Where,

π/2 = 90

θ = x/2

Therefore:

sin(90 – x/2) = cos(x/2)

Answer:

cos(x/2)

A city's record annual rainfall is 40 inches. This year it has rained 37.26 inches. How many more inches of rainfall will match

Brums [2.3K]

Answer: City needs 2.4 inches of rainfall more to match the record of 40 inches.

Step-by-step explanation:

Since we have given that

Total annual rainfall a city record = 40 inches

This year, total rainfall recorded = 37.6 inches

Number of inches of rainfall is needed to match the record of 40 inches is given by

$40-37.6\\\\=2.4\ inches$

Hence, City needs 2.4 inches of rainfall more to match the record of 40 inches.
