To make a model of corresponding angles using toothpicks or straws, you can take two pieces of the material and place them next to each other at the same angle.

When two parallel lines are intersected by another line, corresponding angles are the angles that are created in matching corners or corresponding corners with the transversal.

To make a model of co-interior angles, you can place the two pieces of material on top of each other, with one inside the other at the same angle. To make a model of alternate angles, you can place the two pieces of material on opposite sides of a straight line, with one angle facing up and the other angle facing down.

The total weight of the items is 29.25 lb.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The wight of one can = 13 1/2 = 27/2 pounce

and, number of cans in one case = 12

So,  total weight of the items

= 1/16 ( 27/2 x 12 x 2)+ 4x 2.375

= 1/16 ( 324) + 9.5

= 81/4 + 9.5

= 20.25+ 9.5

= 29.25 lb

Hence, the weight is 29.25 lb.

height of pentagonal prism is h unit.

The prism is one that has two pentagonal bases from which one acts as bottom and the other acts as top. The pentagonal prism has five rectangular sides. This prism has 10 vertices and 15 edges. It is also said five-sided polygon prism.

given, area of pentagonal prism = 34 square unit

volume of pentagonal prism = 180.2 cubic unit

we know the formula for the area of the pentagonal prism.

Total surface area = 5ab + 5hb

Volume of pentagonal prism = 5/2 a b h

where, a =apothem length

b = base length

h = height of the prism

according to the given statement, 34 = 5 a b + 5 h b

          180.2 = 5/2 a b h

from the above two equation, we get, the height of prism = h unit.

The equation of the line with points (0.0) and (-3,-7) is y = 7/3 * x

A coordinate system is a method for determining how to position points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more integers, or coordinates.

The study of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry). Finding the distance between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.

The points are (0,0) and (-3, - 7)

The equation of the line will be

y - 0 = (-7 - 0)/(-3-0) * (x - 0)

Therefore ,the solution to the given problem of angles comes out to be

∠K= 66 degree,LK length = 2√2 unit LK length = 2√2 unit.

In Geometrical, an angled is a structure made up of two rays, known as the angle's face, that converging at the vertex, or center, of the angle. It is feasible for two beams to form an angle within a plane depending on where they are placed. An angle is also created when two planes intersect. The nomenclature to them is diahedral angles. In plane geometry, light rays or lines with the same ending can have many different forms, or angles. The Latin word "angulus," which means "horn," is where the word "angle" in English comes from. The vertex, also known as the vertex of the angle, is the point at where the two rays meet.

Here,

Given: A right angle triangle MKL

∠M = 24 degree

and ∠K =90 degree

Thus,

=> ∠L + ∠M  +∠K =180

=> 90 + 24 + ∠K = 180

=>∠K =180-114

The intersection point in mathematics is the location on the y-axis where the slope of the line passes. a point where a line or curve's y-axis crosses it. This is demonstrated using the equation for the straight line, Y = mx+c, where m denotes the slope and c the y-intercept. The equation's intercept form highlights the line's slope (m) and y-intercept (b). The slope is m and the y-intercept is b when an equation has the intercept form (y=mx+b). It is also possible to rewrite some equations so that they resemble slope intercepts. For example, the slope and y-intercept are both modified to 1 if y=x is rewritten as y=1x+0.

Let us rewrite:

n!+ (n+1)n! = (n+2)(n+1)n!

n!(1+n+1) = (n+2)(n+1)n!

Divide by n!

==> n+2 = (n+2)(n+1)

No divide by (n+2)

The measure of angle TSB is m ∠TSB = 40°.

What is inscribed angle?

In terms of geometry, an inscribed angle is the angle created when two chords intersect within a circle. It can also be described as the angle formed by two specified points on a circle at a given point on the circle. Two chords of the circle sharing an endpoint are equivalently used to define an inscribed angle.

Given:

The measure of arc BR = 100°.

We have to find the measure of angle TSB.

Since the measure of half of the arc is 180°.

⇒       TR = 180°

 TS + BR = 180°

TS + 100° = 180°

          TS = 180° - 100°

          TS = 80°

The measure of arc TS is 80°.

Since,

             TS = 2 m ∠TSB

⇒ m ∠TSB = 1/2TS

   m ∠TSB = 1/2(80°)

  m ∠TSB = 40°.

Hence, the measure of angle TSB is m ∠TSB = 40°.
