Answer:  each angle will be 18.

Step-by-step explanation:

1. in an equilateral triangle all sides are equal.

2. so , perimeter =54

          no. of angles in a triangle = 3

          measurement of each angle = 54/3

                                                          = 18.

Answer 2

Answer:

Correct Question :-

• Find the side of an equilateral triangle whose perimeter is 54 cm.

Given :-

• An equilateral triangle whose perimeter is 54 cm.

To Find :-

• What is the side of an equilateral triangle.

Formula Used :-

★ Perimeter of an Equilateral Triangle = 3a ★

where,

• a = Side

Solution :-

Given :

• Perimeter = 54 cm

According to the question by using the formula we get,

↦ 3a = 54

↦ a = 54/3

➠ a = 18 cm

∴ The side of an equilateral triangle is 18 cm .

VERIFICATION :-

⇒ 3a = 54

By putting a = 18 we get,

⇒ 3(18) = 54

⇒ 3 × 18 = 54

➤ 54 = 54

Hence, Verified.
