Answer:
I'm about 3 months haha, but I'll still help you out. Angle E is equal to 75 degrees.
Step-by-step explanation:
imma go with my gut and say b :?
Atmospheric pressure = 101,325 Newtons / m²
Weight per meter square = 101,325 Newtons
Mass per meter square = 101,325 / (9.81 x 1000)
Mass per meter square = 10.3 tonnes per m²
25/20 × 100% = 125%
125% - 100% = 25%
25% profit :)
