Answer:
12.4967 m
≈ 12.5 m
Step-by-step explanation:
From the solution diagram attached, to find /AB/, we apply sine rule:
AB/Sin 140° =AD/Sin 15°
AB = 10/Sin 15° x Sin 140°
= 24.8372 m
To calculate the height of the pole we will calculate BC first. Using the right angle triangle ∠ABC, we have:
Sin ∅ = BC/AB
Sin 25° = BC/ 24.8372
BC = 24.8372 Sin 25°
= 10.4967 m
The height of the pole = BC + 2.0
= 10.4967 + 2.0
= 12.4967
≈ 12.5 m

Answer: no real solution
Step-by-step explanation:
X^2 - 6 + 9 = 0
Step 1: Simplify both sides of the equation.
x^2+3=0.
Step 2: Subtract 3 from both sides.
x^2+3−3=0−3
x^2=−3.
Step 3: Take square root. x=±√−3
answer is No real solutions.
Answer:
Step-by-step explanation:
Charge on atom is due to electron
Electron have negative charge while proton have positive charge and neutron have no charge. If there are 10 proton (10 positive charge)
You got these prime numbers from a factor tree you need to multiple them together to get 2475
