Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos29° = $\frac{adjacent}{hypotenuse}$ = $\frac{YZ}{XZ}$ = $\frac{12.6}{XZ}$ ( multiply both sides by XZ )

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = $\frac{12.6}{cos29}$ ≈ 14.4 cm ( to 3 significant figures )

The series :

1/5 + 1/10 + 1/15 + 1/20 + 1/25

The series can be expressed as :

a1 = 1 / 5*1

a2 = 1 / 5*2

a3 = 1 / 5*3

a4 = 1 / 5*4

a5 = 1 / 5*5
