Question

An equilateral triangle has a perimeter of 100 cm. How will the perimeter change if one of its angles is made 178°, keeping the area constant?​ a)4 times 4 b)10 times 10 c)20 times 20 d)Near to infinite​

Answer 1

Answer:

d) near to infinity

178° is approximately a straight line & area of a straight line will very small no. which is near to infinity.

Answer 2

The perimeter, if one of its angles is made 178°, keeping the area constant will become near to infinite​.

• The angle of 178° is very close to 180°. An angle that is 180° will make a straight line.
• This means that one of the sides has an angle of 178° with the base and it keeps extending until the third side meets.
• This extension must keep taking place unless the second and the third side don't meet because only then a triangle will be formed.
