Answer:

x ≈ 11.1

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos42° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{15}$ ( multiply both sides by 15 )

15 × cos42° = x, then

x ≈ 11.1 ( to the nearest tenth )

$\sf S \infty \ =a_1 \ x \ \dfrac{1}{1-r}$

Identify following

a1 = 2

r = 1/2

Solve:

$\rightarrow \sf S \infty \ =2 \ x \ \dfrac{1}{1-\frac{1}{2} }$

$\rightarrow \sf S \infty \ =4$
