Find The Length Of Side BC.Give Your Answer To 3 Significant Figures.A716.3 CmB

Answers

Answer 1

Answer:

19.3 cm

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle B = 71°

Adjacent = 6.3 cm

Hypothenus = BC =?

The length BC can be obtained by using cosine ratio. This is illustrated below:

Cos B = Adjacent / Hypothenus

Cos 71 = 6.3 / BC

0.3256 = 6.3 / BC

Cross multiply

0.3256 × BC = 6.3

Divide both side by 0.3256

BC = 6.3 / 0.3256

BC = 19.3 cm

Thus, Lenght of side BC is 19.3 cm

Answers

Answer:

I mean you could have looked it up but, here is the answer...

Step-by-step explanation:

If a quadrilateral is a kite, then its diagonals are perpendicular. If a quadrilateral is a kite, then exactly one pair of opposite angles are congruent. If a quadrilateral is a kite, then one of the diagonals bisects the pair of non-congruent angles.

Kites or kite shapes have at least one pair of congruent opposite angles, and the provided statement is correct.

What are the properties of Kite shapes?

A kite is a closed shape quadrilateral which have 4 sides. In this 4 sides, the two pair of adjacent sides are equal.

Properties of kite shapes are listed below-

Two pairs of adjacent sides are equal in a kite shape.The kite has a pair of opposite angles which are equal.The long diagonal bisect the short one.Both the diagonals of the kite is perpendicular to each other.

As, the kites has a pair of opposite angles which are equal.

Thus, Kites or kite shapes have at least one pair of congruent opposite angles, and the provided statement is correct.

Please help

Answers

Answer:

B

Step-by-step explanation:

The range is all numbers that Y can range from, so looking at the chart we can see that the highest value on the top of the curve that Y reaches is 4. Looking at the very start of the line and the very end of the line, you can see that -inf is definitely in the range of the y values. So, we can write it like this:

-inf<y<=4

which happens to be B

Range here should be option (b)

The area, A, of a triangle is one-half the product of the triangle's base and height. A = A = (12)(5) A = ( b+ h) A = A = (b·h)

Answers

Answer:

A = (1/2) * b * h

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, right angle, equilateral and isosceles triangle.

The area of a triangle is half the product of the base of the triangle and the triangle height. The area is given by the formula:

A = (1/2) * b * h

A = (1/2)bh  = 0.5bh

Where A is the area of the triangle, b is the bae of the triangle and h is the height of the triangle.

Step-by-step explanation:

The given equations are:

[tex]y + 3x =-4\ \ \ Eqn\ 1\\2x-3y =-21\ \ \ Eqn\ 2[/tex]

The equations have to be solved using substitution method. In substitution method we find the value of a variable from one equation and put it in the other equation.

To find the value, we usually choose the equation in which a variable without any coefficient is available.

From equation 1

[tex]y +3x = -4\\y = -3x-4\\[/tex]

Where these two worlds collide, animals almost never farewell. Highways, where humans speed by large tracts of natural habitat like missiles of doom, are especially dangerous for wild creatures. They can also be deadly, not just for individual animals but for entire species. The Florida panther, for example, has such a low population that each time one is killed on a highway, it is a catastrophic loss.There is hope, however, in a new way of helping animals cross through highway areas unharmed. Wildlife overpasses give animals a way to cross highways without risking their lives. These look and work like bridges but are usually covered with grass and trees that make animals like deer feel welcome. The cars drive through a tunnel under the bridges. Fences along the top edges keep the animals safe.These overpasses also connect habitats, so along with deer, the coyotes who hunt them can cross. This allows both species to have a larger range, which also helps their long-term survival. To the animals in these habitats, the overpasses may be like an extra safety net that helps them survive a drought. The bridges are especially important for animals that migrate. For centuries, animals like elk and buffalo migrated on trails that still, now, lead right up to the edges of major highways. With the help of these bridges, migrating animals can still follow their long-used paths unharmed.In some cases, these overpasses benefit humans directly as well. In these cases, the overpasses are part of green space or parks that people use for cycling, backpacking, or jogging. The overpasses give humans access to areas they may not have been able to see but also provide safety for animals.The next time you are traveling on a highway, keep a lookout for a wildlife passage. With attention to how our lives affect the natural world, we can find clever solutions, like wildlife passages, that help animals and improve our lives, too.Extra! Extra!Not all wildlife accommodations for highways are overpasses. In some cases, certain species are so important that underpasses or underground tunnels are built. In Florida, two such underpasses help turtles, snakes, and alligators that often migrate from one body of water to another. Since these creatures do not have much speed, crossing a highway for them is even more deadly than it is for swift animals like deer. Working as a large funnel, these underpasses usually require a barricade or fence alongside the highway that forces animals toward a tunnel. Aquatic turtles especially benefit from these tunnels as they lay eggs in holes dug in dry ground, away from the lake they live in.what benefit do overpasses and underpasses offer wildlife?A. A view of passing humans and carsB. Access to habitat that helps them surviveC. Attention to the need for additional habitatD.
