Lets try
centimeter is about 1/2 of a inch

if 28 square cm, the book coould be about 4m by 7cm (aoub the size of a recipt)

if 28 square in the book could be about 4in by 7in (regular size)

I would guess 28 square INCHES (cm is too smal)

PLEASEEEEE HELP ASAP!!!

Ne4ueva [31]

Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle

AB represents the hypotenuse of the right angle triangle.

With m∠A as the reference angle,

AC represents the adjacent side of the right angle triangle.

BC represents the opposite side of the right angle triangle.

To determine AB, we would apply the Cosine trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos 52 = 10/AB

0.616 = 10/AB

AB = 10/0.616

AB = 16.23

If A=30°, a=12, b=28 how many triangles can be constructed?

Fofino [41]

Check the picture below.

recall the ambiguous SSA case, as the "12" side moves, it ends up with two supplementary angles on the base.

Pascale leaves the office to go home. She walks 12 blocks due north and then 9 blocks due west. How far is she from the office?

Stells [14]

Answer:

15 blocks

Step-by-step explanation:

We can use the Pythagorean theorem to solve the right triangle

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

12^2 + 9^2 = h^2

144+81 = h^2

225= h^2

Taking the square root of each side

sqrt(225) = sqrt(h^2)

15 = h

What are the steps for constructing a copy of an angule only a compass and a straightedge

nlexa [21]

With one point of the compass on the vertex of the angle, draw an arc that intersects both sides of the angle. Draw an arc from each of these points of intersection so that the arcs intersect in the interior of the angle. The compass needs to stay open the same amount throughout this step.

I hoped that help..have a great day:)

I did 3 over 7 then 8 over x. I'm getting decimals. ‍♀️

Answer:

The length of side b is 9.

Step-by-step explanation:

Triangles are similar if they have the same shape, but can be different sizes.

When two figures are similar, the ratios of the lengths of their corresponding sides are equal.

If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. We know that the triangle $ABC$ is similar to the triangle $XYZ$ . Therefore the following relation must be true:

$\frac{AB}{AC} =\frac{XY}{XZ}$

We know that side $AB$ is equal to 8, side $AC$ is equal to b, side $XY$ is equal to $2\frac{2}{3}$ , and side $XZ$ is equal to 3.

Substituting these values into the above relation and solving for b we get that:

$\frac{8}{b} =\frac{2\frac{2}{3} }{3}\\\\\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 2\frac{2}{3}=\frac{8}{3}\\\\\frac{8}{b}=\frac{\frac{8}{3}}{3}\\\\8\cdot \:3=b\frac{8}{3}\\\\24=b\frac{8}{3}\\\\8b=72\\\\b=9$
