Here,
X = 6 units
Y = 8 units
Z = 10 units
Then,
Semi-perimeter = (X+Y+Z)/2
= (6+8+10)/2
= 12units
Area of triangle XYZ = { s(s-x)(s-y)(s-z)} ^1/2
= { 12(12-6)(12-8)(12-10)}^1/2
= [12*6*4*2]^1/2
= (576)^1/2
= 24 unit^2
Now,
Area of triangle XYZ = 1/2 * Y * Z * ◀B
24 units^2 = 1/2 * 8 * 10 * ◀B
24 = 40 * ◀B
24/40 = ◀B
3/5 = ◀B
◆D) ◀B = 3/5
It is a Right Answer...
