The unit for area of a triangle is square units.

The area of a triangle is the amount of two-dimensional space that it occupies.The law of cosines to calculate the length of the third side, and then use the formula to calculate the area.

The formula for calculating the area of a triangle is A = ½ × base × height. The unit for the area of a triangle is typically square units such as square meters (m2), square kilometers (km2), square feet (ft2), and square inches (in2).To calculate the area, you need to measure the base and height of the triangle and multiply them together. Then, you need to divide the product by two. For example, if the base of the triangle is 4 cm and the height is 6 cm, then the area A = ½ × 4 cm × 6 cm = 12 cm². Therefore, the area of the triangle is 12 cm².

The area of triangle if sides are 9cm 12cm and 15cm is 54 square cm.

In the given question we have to find the area of triangle if sides are 9 cm 12 cm and 15 cm.

The entire area bounded by a triangle's three sides is referred to as the triangle's area. In essence, it equals half of the base times height, or A = 1/2bh. So, in order to calculate the area of a triangular polygon, we need to know its base (b) and height (h).

Area of Triangle = 1/2 bh

Area of Triangle = 1/2 9*12

Area of Triangle = 9*6

Area of Triangle = 54 square cm

Hence, the area of triangle if sides are 9cm 12cm and 15cm is 54 square cm.

The solution to the system of equations y = -3x - 2 and 5x + 2y = 15 is (-19, 55).

A system of linear equations is a set of two or more equations which includes common variables. The solution to a system of equations, is the value of the unknown variables used in the equations that satisfies both equations.

Given two linear equations in x and y,

y = -3x - 2     (equation 1)

5x + 2y = 15     (equation 2)

Use substitution method to find its solution. Since the first equation is already expressed as y in terms of x, substitute the first equation to the second equation.

5x + 2y = 15     (equation 2)

5x + 2(-3x - 2) = 15

5x - 6x - 4 = 15

Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solve for x.

5x - 6x - 4 = 15

-x = 15 + 4

x = -19

Substitute the value of x in the first equation and solve for y.

y = -3x - 2     (equation 1)

y = -3(-19) - 2

y = 55

Hence, the solution of the given system of equations is (-19, 55).

x < 3 is a solution of the inequality x - 3 < 0 and x < 3 is not the solution of the inequality x + 3 < 0.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Suppose that the inequality is x - 3 < 0.

x - 3 < 0

Adding 3 on both sides of the equation,

x - 3 + 3 < 0 + 3

x < 3

x< 3 is the solution of the expression x - 3 < 0.

Consider the inequality x + 3 < 0.

x + 3 < 0

Subtracting 3 from both sides,

x + 3 - 3 < 0 - 3

x < -3

x < 3 is not the solution of the expression x + 3 < 0

Hence the expression with x < 3 as a solution is x - 3 < 0 and not as a solution is x + 3 < 0.

Abby can make 26 tie-dyed T-shirts.

We can start by setting up a linear equation to represent the total cost of making the tie-dyed T-shirts.

What is a linear equation?

First-order equations include linear equations. In the coordinate system, linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., just one variable).

Multiple variables may be present in a linear equation. Linear equations with two variables, for example, are used when a linear equation contains two variables.

Let x be the number of T-shirts Abby makes

The cost for each T-shirt is $3.95 + $0.50 = $4.45

The cost of the two boxes of salt is $4.50 * 2 = $9

So the total cost for x T-shirts is $4.45x + $9

We know that the total cost is 124.70 and we want to find the value of x, so we can set up the equation as:

$4.45x + $9 = 124.70

Solving for x:

$4.45x = 115.70

x = 115.70 / 4.45

x = 26

Therefore, Abby can make 26 tie-dyed T-shirts.

The value of all the missing angles of the triangle are;

m∠RPQ = 30°

m∠PQR = 72°

m∠PRS = 39°

m∠RPS = 15°

m∠PQS = 36°

m∠PSR = 126°

The incenter of a triangle is the intersection point of all the three interior angle bisectors of the triangle.

Now, the sum of angles in a triangle is equal to 180 degrees. We are given;

m∠PRQ = (8x - 10)°

m∠RPQ = (4x - 14)°

m∠PQR = (7x - 5)°

Thus;

(8x - 10) + (4x - 14) + (7x - 5) = 180

19x - 29 = 180

19x = 209

x = 209/19

x = 11

Thus;

m∠PRQ = (8(11) - 10)° = 78°

m∠RPQ = (4(11) - 14)° = 30°

m∠PQR = (7(11) - 5)° = 72°

By the definition of incenter of a triangle, we can say that;

m∠PRS = 78°/2 = 39°

m∠RPS =  30°/2 = 15°

m∠PQS = 72°/2 = 36°
