please answer it urgently please the perimeter of an isoscles triangle is 42 cm and its base is (3/2) times each of the equal sides. find the length of each side of the triangle, area of the triangle and the height of the triangle.

Answer»

Let X is one side of triangle
42=x+x+3/2x
42=2x+3/2x
42=2+3/2x
42=7/2x
42×2/7=x
x=2×6
x=12
now12 is one side
2 side is 24
then BASE = 42-24 =18
half of base is 9
by USING Pythagoras
12^2=9^2+height^2
height^2=114-81
height ^2=33
height=√33

Meaning of this sign in maths

Answer»

Answer:

thats alpha

Step-by-step explanation:

Mathematics is a language, in that it ALLOWS us to express ideas and notions that are hard or impossible to communicate otherwise. Music is a language in precisely this sense, too.

Mathematics is FAR more than just a language, though. It is more than a way of communicating and expressing ideas. It has theorems, truths, proven FACTS about things. That is something that languages simply lack.

Those theorems are expressed in MATHEMATICAL language, but they aren't MERELY that language. This is why I feel that "mathematics is a language" doesn't quite capture what math is.
