Answer:

D. $Cos(Z) = \frac{5}{13}$

Step-by-step explanation:

Using trigonometric ratios formula, thus:

$Cos(Z) = \frac{Adjacent}{Hypotenuse}$

Reference angle = Z

Adjacent = 10

Hypotenuse = 26

Plug in the values into the formula

$Cos(Z) = \frac{10}{26}$

Simplify

$Cos(Z) = \frac{5}{13}$

Answer:

10.5 ft

Step-by-step explanation:

In ΔQRS,

m∠S=90°
m∠R=29°,
SQ = 5.8 feet.

See the diagram below.

The triangle is a Right Triangle,

Using trigonometric ratios,

$Tan R=\dfrac{|SQ|}{|RS|} \\Tan 29^\circ=\dfrac{5.8}{|RS|}\\$Cross multiply$\\|RS|XTan 29^\circ=5.8\\|RS|=\dfrac{5.8}{Tan 29^\circ}\\$=10.5 ft (to the nearest tenth of a foot)$
