Question

is the statement correct,,,,,,,,,,,,plse help me

Construct a triangle abc in which bc = 5 cm , angle c =60 and ac-ab = 1.5 cm

Answer 1

just say true or false ? i didnt understand with the question --"

Answer 2

ac-ab = 1.5 cm is written correct or not
or it should be ab-ac=1.5 cm

Answer 3

hmmm... i caught it, we need prove is this triangle or not according the values given above.

let AB = x
AC = x + 1.5
cos60 = [5^2 + (x+1.5)^2 - x^2]/(2*5*(x+1.5))
1/2 = [25+3x+2.25]/(10x+15)
10x+15 = 55+6x
4x = 40
x = 10

so, AB = 10, AC=11.5, and BC=5
whatever, it is a triangle, because :
10+11.5 > 5
10+5 > 11.5
5+11.5 > 10
(MAYBE)
