Answer:
15 m
explanation:
Let AB and CD be the pole and tower respectively. Let CD=h Then ∠DAC=60 ∘ and∠DBE=30 ∘ Now CA CD =tan60 ∘ = 3 ∴CD= 3 CA⇒ 3 h =CA Again BE DE =tan30 ∘ = 3 h ∴(h−10)= 3 BE = 3 CA ...[∵BE=CA] = 3 h/ 3 = 3 h ⇒3h−30=h⇒2h=30⇒h=15
Hence, height of the power =15 m
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the line above

Answer:
22.1
Step-by-step explanation:
If the triangle is similar then the side lengths have common ratios
*Create ratio to solve for RS*
47.8/13 = RS/6
Now solve for RS
simplify
47/13 = 3.677
We now have 3.677 = RS/6
Multiply each side by 6
3.677 * 6 = 22.1
RS/6 * 6 = RS
we're left with RS = 22.1
