How to sketch an angle in standard position

Answers

Answer:

Drawing an angle in standard position always starts the same way, draw the initial side along the positive x-axis. To place the terminal side of the angle, you must calculate the fraction of a full rotation the angle represents.

Answer:

Get the number of rotations of the given angle by dividing 360 degrees with respect to positive x-axis.

Step-by-step explanation:

1. First draw a horizontal line (along x-axis).

2. Locate the terminal side of the angle by dividing 360 degrees. Recall that one full rotation is equal to 360 degrees.  So, to sketch 360 degrees, we will divide it by 360 degrees resulting in 1.

3. Similarly to draw 180 degrees, divide 180 by 360. This will result in 1/2. Therefore, it is half the way from x-axis.

ABC form a triangle where BAC equals 90° a B equals 10.8 mm and C equals 1.6 mm find the length of BC give your answer rounded to one DP
Please really need help it’s for a test

Answers

Answer:

BC = 10.9 mm

Step-by-step explanation:

The computation of the BC is given below:

Here we applied the pythagorus theorem

AB = 10.8 mm

AC = 1.6mm

BC = ?

Now as we know that

AB^2 + AC^2 = BC^2

10.8mm^2 + 1.6mm^2 = BC^2

116.64mm^2 + 2.56mm^2 = BC^2

BC = 10.9 mm

What is a Proportional Relationship?

If m is the slope or unit rate, a proportional relationship between two variables, x and y, can be represented with an equation as, y = mx.

Let's find the equation that represents the relationship represented by the graph and the table. Let's use the graph.

m = y/x

Using the point, (2, 4),

m = 4/2 = 2

Substitute m = 2 into y = mx

y = 2x

Therefore, the equation of the proportional relationship represented by the table and the graph is: y = 2x.

Answer:

The missing angle is 65°

Step-by-step explanation:

For context, all triangles' angles will always add up to 180°. The outside angle of S is supplementary to the inside angle, so in order to find S:

180 - 153 = 27°

<TSU = 27°

S = 27°

U = 88°

As mentioned before, angles of triangles will add up to 180. In order to find the missing angle (?) we will add the other two sides and subtract them from 180.

27 + 88 = 115

180 - 115 = 65°

Answers

Answer:

The height is 15 cm. The volume is 6000 cm³

Step-by-step explanation:

The base is square, so the sides are equal.

√400 = 20. This is the length and width of the cuboid.

The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.

2000 - 800 = 1200 cm²

Divide by 4 to get the area of an individual face.

1200/4 = 300 cm²

We found the width earlier: 20cm

We found the width earlier: 20cm300/20 = 15cm. This is the height.

To find Volume, multiply Area of the base times the height:

400cm²×15cm = 6000cm³

Answer:

this is your answer. best of luck.

Answer:

length = 20cm

breadth = 8cm

Step-by-step explanation:

solution;

length(l) = x + 12

breadth(b) = x

perimeter (p) = 56 cm

we know that,

perimeter(p) = 2(l + b)

or, 56 = 2(x + 12 + x)

or, 56 = 2(2x + 12)

or, 56 = 4x +24

or, 56 - 24 = 4x

or, 32 = 4x

or, 32 / 4 = x

x = 8

now

putting the value of x in length and breadth

length = x+ 12

=8 + 12

=20cm

breadth = 8cm

to find out he marks up each shirt by, just do 45% of 6 or 0.45 * 6 = $2.70

If Jerry buys a t-shirt for $6 and sells it for 45% more than she bought it, then jerry is selling them for $8.70 and making $2.70 for each t-shirt she sells, because 45% of 6 is 2.7
