<h3>Answer:  60 units</h3>

=====================================================

Explanation:

The similar red marks on the angles tell us those angles are congruent. So they are the same measure.

The sides opposite those congruent angles are the same length. This means AC = BC. This triangle is isosceles.

--------------

Solve for x

AC = BC

5x-8 = 2x+7 .... substitution

5x-8-2x = 7 ... subtract 2x from both sides

5x-2x = 7+8 ..... add 8 to both sides

3x = 15

x = 15/3 ... divide both sides by 3

x = 5

---------------

Use that x value to compute each side length

AB = 3x+11 = 3*5+11 = 15+11 = 26

BC = 2x+7 = 2*5+7 = 10+7 = 17

CA = 5x-8 = 5*5-8 = 25-8 = 17

Note how BC and CA are the same length (17 units). This helps confirm we have the right x value.

----------------

The last step is to add up all the side lengths to get the perimeter

perimeter of triangle = sum of all the sides

perimeter of triangle = side1 + side2 + side3

perimeter of triangle ABC = AB + BC + CA

perimeter of triangle ABC = 26 + 17 + 17

perimeter of triangle ABC = 60 units

Exercise 1:
 
exponential decay:
 The function is given by:
 y = A (b) ^ ((1/3) * t)
 Where,
 A = 600
 We look for b:
 (480/600) * (100) = 80%
 b = 0.8
 Substituting:
 y = 600 * (0.8) ^ ((1/3) * t)
 We check for t = 6
 y = 600 * (0.8) ^ ((1/3) * 6)
 y = 384
 Answer:
 
exponential decay:
 
y = 600 * (0.8) ^ ((1/3) * t)
 Exercise 2:
 
linear:
 The function is given by:
 y = ax + b
 Where,
 a = -60 / 2 = -30
 b = 400
 Substituting we have:
 y = -30 * x + 400
 We check for x = 4
 y = -30 * 4 + 400
 y = 280
 Answer:
 
linear:
 
y = -30 * x + 400
 Exercise 3:
 
exponential growth:
 The function is given by:
 y = A (b) ^ ((1/3) * t)
 Where,
 A = 512
 We look for b:
 (768/512) * (100) = 150%
 b = 1.5
 Substituting:
 y = 512 * (1.5) ^ ((1/2) * t)
 We check for t = 4
 y = 512 * (1.5) ^ ((1/2) * 4)
 y = 1152
 Answer:
 
exponential growth:
 
y = 512 * (1.5) ^ ((1/2) * t)
