An equilateral triangle has sides of length s. If each side is increased by 15, represent the new perimeter in terms of s.

1 answer:

5 0

We know that an equilateral triangle has all sides equal.
Initial perimeter = s + s + s = s
Each side has been increases by then the new perimeter is:

(s+15) + (s+15) + (s+15) = 3s + 45

So the new perimeter = 3s + 45

Answer:

x = 30°

Step-by-step explanation:

Since 2 of the sides are congruent then the triangle is isosceles and the 2 base angles are congruent, both 75°

The sum of the 3 angles in a triangle = 180°, then

x = 180° - (75 + 75)° = 180° - 150° = 30°
