Once upon a time, there was a girl called Rachel, who studied at a school called Mery Mazzarello. Rachel was very happy but her classmates were very mean to her a...
8 = 4
a = (8-a) Cross multiply.
64-8a = 4a
64 = 12a
a = ⅓(16) cm.
b = 8-a
b = ⅓(8) cm.
c = atan(⅔)°
d = atan(3/2)°
⅔ = 8/e
e = 12 cm
⅔ = f/8
f = ⅓(16) cm.
g = 8-f
g = ⅓(8) cm.
Area Orange ex...
The radius of the inscribed circle is 2 units.
a = 2atan(⅓)°
b = 2atan(⅕)°
c = 180-a-b
c = (180-2atan(⅓)-2atan(⅕))°
sin(2atan(⅓)) = d/16
d = (48/5) units.
cos(2atan(⅓)) = e/16
e = (64/5) units....

Let x² = p
Calculating p.
(4-p)^⅓+(p-1)^½ = 1
4-p = (1-(p-1)^½)³
4-p = (p-2(p-1)^½)(1-(p-1)^½)
4-p = 3p-p(p-1)^½-2(p-1)^½+2p-2
(p+2)((p-1)^½) = 4p-6
p-1 = ((4p-6)/(p+2))²
(p-1)(p²+4p+4) = 16p²...

Let a be the side of the square.
cos30 = b/8
b = 4√(3) cm.
sin30 = c/8
c = 4 cm.
a = b+12
a = (12+4√(3)) cm.
Area Square is;
a²
= (12+4√(3))²
= 358.27687752661 cm²
d² = 12²+4²-2*4*12cos30
d...

Let the square side be 2 units.
Area square is;
2²
= 4 square units.
Calculating Area A.
a² = 2²+1²-2*2*1cos45
a = √(5-2√(2)) units.
(√(5-2√(2))/sin45) = (2/sinb)
b = asin(√(2)/(√(5-2√(2))))°...
