Mathematics Question and Solution
a = 2+2
a = 4 units.
b = a-½(2)
b = 4-1
b = 3 units.
c² = 2(3²)
c = √(18)
c = 3√(2) units.
d² = (3√(2))²+4²-2*3√(2)*4cos45
d = √(10) units.
d = 3.1622776602 units.
d is the radius of the circle.
Let the required angle, alpha be e.
It implies;
Calculating e.
(√(10)/sin45) = (4/sine)
e = 63.4349488229°
e = (45+atan(⅓))°
Again, e is alpha the required angle.
Or
Angle alpha, e is;
g = 4-3
g = 1 unit.
tanf = 1/3
f = atan(⅓)°
Therefore;
e = 45+f
e = (45+atan(⅓))°
e = 63.4349488229°
