(x+3)(x+2)=0 ↔ zero product property and

(x+3)(x+2)=0 ↔ square root property.

Solution:

Given expressions are (x+3)(x+2)=0 and x^{2}+6=31.

To find which techniques is most appropriate to solve each equation.

Equation 1: (x+3)(x+2)=0

Zero product property states that if AB = 0 then A = 0 or B = 0.

In the equation is (x+3)(x+2)=0, zero product property is used to solve the equation.

(x + 3) = 0 (or) (x + 2) = 0

x = –3 (or) x = –2

Equation 2: x^{2}+6=31

Subtract 6 from both sides of the equation.

x^{2}+6-6=31-6

x^{2}=25

x^{2}=5^2

Take square root on both sides of the equation.

x = 5

Square root property is used to solve the equation.

Hence (x+3)(x+2)=0 ↔ zero product property and

(x+3)(x+2)=0 ↔ square root property.

Drag a vertex of the triangle to change its shape.
likoan [24]

Answer:

The correct option is;

45°

Step-by-step explanation:

By angle sum theorem, we have that the sum of angles in a triangle = 180°

Therefore, we have;

When the interior angles of the triangle are constructed to be 60° and 75°, we have by the angle sum theorem;

The third angle + 60° + 75° = 180°

Which gives;

The third angle  = 180°- 60° - 75° = 180°- 135° = 45°

The measurement of the third angle by the angle sum theorem will be 45°

The correct option is ∠third angle = 45°.
