Answer:
Shape of Triangular sail is Obtuse Angled Triangle.
Step-by-step explanation:
The triangle is obtuse since the sum of the squares of 2 sides are greater than the square of the third side. (Converse Pythagorean theorem) Hope this helps!
Given: Length of sides of triangular sail = 7 ft , 15 ft , 7 ft
To find: Shape of Sail .i.e., shape of triangle
We use a result which states that
if a , b , c are sides of triangle where c is greater then a & b.
now, if c² < a² + b² then triangle is Acute angled
if c² = a² + b² then triangle is Right angled
if c² > a² + b² then triangle is Obtuse angled
here a = 7 , b = 7 & c = 15
c² = 15² = 225
a² + b² = 7² + 7² = 49 + 49 = 98
since, c² > a² + b²
⇒ Triangle must be Obtuse Angled.
Therefore, Shape of Triangular sail is Obtuse Angled Triangle.
