Let alpha be x.
6x = 60
x = 10°
Alpha is 10°
Check accuracy.
x+x+2x+8x+6x = 18x
And x = 10
Therefore;
18x = 18*10 = 180° which is the sum of the interior angles of the ascribed t...
(m+n)² = c²+b²-2bccosA --- (1).
h² = c²-m²
c² = h²+m² --- (2).
h² = b²-n²
b² = h²+n² --- (3).
Substituting (2) and (3) in (1).
(m+n)² = h²+m²+h²+n²-2bccosA
m²+2mn+n² = 2h²+m²+n²...
