Screenshot of yesterday's teaching and learning activities with super smart and clever Adesuwa (year 5), and Oghosa (year 7).
Educators;
Mr. Daniel, Mr. Ovo
We are smart and clever.
a² = 6²-1²
a = √(35) units.
b = atan(√(35))
cos(atan(√(35))) = c/2
c = â…“ unit.
Where c is CE.
d = atan(√(35))-60
d = 20.40593177314°
Where d is angle FCE.
tan20.40593177314 = e/(1/3)
e = 0.12400...
EG = DG = ½√(12²+6²)
EG = DG = 3√(5) cm.
Ang CDE = atan(½)
It's implies;
(CG)² = 45+144-2*36√(5)cos(atan(½))
CG = 3√(5) cm.
CG = 6.7082039325 cm.
tan(atan(½)) = a/6
a = 3 cm.
b = 12-3
b = 9 cm....
Calculating angle ABD.
Let it be a.
Using cosine rule.
25 = 36+9-2*18cosa
36cosa = 45-25
a = acos(20/36)°
a = acos(5/9)°
Calculating x.
Using cosine rule.
x² = 36+144-2*6*12cos(acos(5/9))
x² =...
BC = √(√(3)²+1²)
BC = 2 units.
Let r be the radius of the circle.
Using similar triangles ratio rule on triangle ACE and triangle BCE to calculate r.
1 = √(3)
√(3) = AE
Cross Multiply.
AE= 3 un...
Let the square side be a.
tan60 = a/b
b = a/tan60 cm.
Where b is BS.
Calculating a.
2b+a = 6
2(a/tan60)+a = 6
a((2/tan60)+1) = 6
a = 6/((2/tan60)+1)
a = 6(2√(3)-3) cm.
Area Shaded STR is;
½(a²)...

Notice;
Diameter of the ascribed semi circle is 20 cm.
Radius, r will be 10 cm.
Calculating Area Shaded.
It will be;
Area half circle with radius 10 cm - 2(area semi circle with radi...
