Answer:
0.25
Explanation:
Since line AB = 5*sq root of 2, that tells us triangle ADB is an isoceles right triangle with legs=5. Therefore, triangle ACD is also an isoceles right triangle and so angle ACD (or B) = 45 degrees. One radian = 180/pi or 57.2958. Therefore angle ACB in radians is 45/57.2958 = .7854 = H*Pi. So H = .7854 / Pi = .7854 / 3.14159 = .0.25

<h3>What are the building construction members?</h3>
The architectural construction method that consists of two uprights and a crossbeam is called post-and-lintel system. This is because in building construction, a system in which two upright members, the posts, hold up a third member, the lintel, laid horizontally across their top surfaces.
The post-and-lintel system is a simple method of construction involving the use of vertical and horizontal elements. The verticals support the horizontals, creating one Storey of a building. Additional verticals can be placed atop the horizontals to create structures with more than one level.

Let a, b, and c be the coefficients in the balanced reaction:
a Fe + b Cl₂ → c FeCl₃
Count the atoms that show up among the reactants and products. They should be equal on both sides:
Fe : a = c
Cl : 2b = 3c
Let c = 2. Then a = 2 and 2b = 6, so b = 3.
Then the balanced reaction is
2 Fe + 3 Cl₂ → 2 FeCl₃
