you plug in the 15

do 14-15

Using a pair of compasses and a ruler only,construct ∆ABC where
LenKa [72]

1.Drawn a straight line AB=7 cm with the help of ruler.

2.With the help of compass drawn an arc from A and at the point where it cuts AB from that point made another arc drawn an arc cutting the previous arc.

3.From A drawn a straight line joining the arc and extend it to M.

4.With the help of ruler measured 5 cm and mark it as AC.

5.Joined BC and we get the required triangle.

6.From C drawn an arc and make it cut on AC and BC and from the point it cuts AC and BC drawn arc cutting each other and extend a line from point C extend a line to the point point of intersection of two arc.

7.Similarly we do for A and the point where the two line intersect denoted as O.

8.Made a perpendicular from O on AB this perpendicular will be radius and taking O as centre we draw a circle this is our incircle.

9.And AN is our locus of points equidistant from two lines AB and AC.

We need to construct a circle inscribed in triangle that is incircle it can be done by making angle bisector of two sides the point where it intersect will be incentre. The centre of required circle.

The angle bisector is the locus where points are equidistant from two sides.

Select the correct answer. Lacy is making a new sail for her boat. The sail needs to have the given dimensions. Approximately ho
Julli [10]

70.1 ft² of fabric is needed by Lacy to make the sail boat.

<h3>Trigonometric ratio</h3>

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let b represent the base of the triangle and h the height, hence:

sin(60) = h / 18

h = 15.6 feet

sin(30) = b / 18

b = 9 feet

The area of triangle = (1/2) * b * h = 0.5 * 9 * 15.6 = 70.1 ft²

70.1 ft² of fabric is needed by Lacy to make the sail boat.

Base 17 area 18.7 how to find missing dimension
rewona [7]
A=bh. You are trying to find the missing dimension which is height. You can set up an equation. 18.7=17h. Divide 18.7 by 17, and you get 1.1, so the height is 1.1

Describe a point. what could you use as a model of a point ?
NNADVOKAT [17]

A point is an exact location.
It has no length, width, or height.
It has no area or volume.
It has no mass, shape, or other physical properties.

As a model ...

-- you could use the period at the end of a sentence printed on paper.
     It looks like this  ==> ·

-- You could use the point of a very sharp pencil.

-- You could use the tiny dot that the point of
a very sharp pencil makes on paper.

-- You could use the point of a pin.

-- You could use the tiny hole that the point of
a pin makes in a sheet of paper.

These are all bigger than a real point.  They all have a little bit of size,
length, width, height, and you can see them.  But they get the idea across.
(They 'make the point'.)
