Answer:
The simplest radical form is option D
4 + 2 = 6
30 / 6 = 5
5 * 4 = 20
5 * 2 = 10
20 : 10
Simplified =
2 : 1
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
