Let the height of the quadrilateral with parallel sides 7 cm and 9 cm be a.
b =√(a²+4) cm.
c = ½√(a²+4) cm.
d = √((½√(a²+4))²-1)
d = √(¼(a²+4)-1)
d = √(¼(a²))
d = ½(a) cm.
½(a) = 8
1 = e,...

Once upon a time, there was a kitten called Adam, who loved reading. When his friends called him to go playing, he never wanted to go.
One day,...
Radius, r of the inscribed semi circle is 6 cm.
sin60 = a/6
a = 3√(3) cm.
b = 12-a
b = (12-3√(3)) cm.
tanc = 3/(12-3√(3))
c = 23.793976887°
c = angle GCB.
d = 180-60-23.793976887
d = 96.20602311...
Calculating r, radius of the circle.
(r/tan40)+(r/tan30) = 10
r = 3.42020143326 cm.
(a/sin60) = (10/sin40)
a = 13.47296355334 cm.
tan40 = 3.42020143326/b
b = 4.07603734548
(4.07603734548/sin50)...

Notice;
AB = 25 units.
cos30 = 8√(3)/a
a = 16 units.
tan30 = b/(8√(3))
b = 8 units.
Let the side of the regular hexagon be c.
c = ¼(AC)
Calculating AC.
((AC)/sin46) = (25/sin74)
AC = 18.708219...

When John arrived home, he went to introduce his new friends to the car, but was so disappointed when none of the toys spoke....
Semicircle radius is 5 cm.
Circle radius is 4 cm.
5² = (5-x)²+√(16-x²)²
25 = 25-10x+x²+16-x²
10x = 16
x = 16/10
x = (8/5) cm.
y = 5-x, and x = 8/5 cm.
y = 5-(8/5)
y = ⅕(17) cm.
PQ is;
2√(5²-(17/...
