use trig to determine the value of x for the right triangle. Round answer to nearest tenth. Show work and explain

Answers

Answer 1

Answer:

15.4

Step-by-step explanation

From the diagram, we are given;

Adjacent = 12

Hypotenuse=x

Angle of elevation =39°

Using the SOH CAH TOA identity

Cos 39 = 12/x

x = 12/cos39

x = 13/0.7771

x = 15.44

Hence the value of x to nearest tenth is 15.4

Joe wants to buy a $180 number that's on is on sale the snowboard is 30% off what is the sale price of the snowboard (show work)

Answers

Answer:

Step-by-step explanation:

Assuming that the Skateboard is $180, and you are asking for the price when it is 30% off.

180 * .70 = $126

Another way of solving the question is finding 10 % of 180, which is 18. And you are looking for 30% less, so 18 * 3 = 54, which is 30% of 180.

180 - 54 = 126

54 is the correct answer

Anthropologists approximate the height of a primate by the size of its humerus (the bone from the elbow to the shoulder) using the equation

H = 1.2L + 27.8,

where L is the length of the humerus and H is the height, in inches, of the primate.

An anthropologist estimates the height of a primate to be 60 in. What is the approximate length of the humerus of this primate? Round to the nearest tenth of an inch.

Answers

Answer:

26.83

Step-by-step explanation:

H=1.2L + 27.8

60=1.2x+27.8

minus 27.8 from both sides

32.2=1.2x

divide both sides by 1.2

Answer:

Complementary angles, adjacent angles

Step-by-step explanation:

Which relationships describe angles 1 and 2?

Options: Complementary angles, vertical angles, supplementary angles, adjacent angles

Angles 1 and 2 are opposite to the 90° angle. So, the angles' relationship to that angles is a vertical angle, meaning that the two add up to 90°.

Complementary angles add up to 90°, so this option is correct.

Vertical angles are the pairs of opposite angles formed by two intersecting lines. Because the two angles do not follow this definition, this option is incorrect.

Supplementary angles add up to 180°. However, we know that the two add up to 90°, so this option is incorrect.

Adjacent angles are angles that are next to each other, so this option is correct.

I hope this helps! Feel free to ask any questions!

Which two statements best defined a them of poem? CAN SOMEONE PLZ TAKE THE TIME TO READ THIS PLZZZZZZZZ!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!From Enemy to FriendWolves and dogs are closely related. Most scientists believe that dogs ancestors were wolves. Through time, wolves became tame enough to live with humans and help them. The change from wolf to dog was probably a result of careful breeding. Early humans allowed only the friendliest wolf pups to remain near them. This ensured that, over time, the wolves that stayed with groups of humans became tamer and tamer.Wolves were influenced by their relationship with humans. So, they slowly became what we know today as dogs. They became adept at protecting and herding sheep and other animals whereas their ancestors would have made a meal of them. This ability made dogs very useful. However, although they are quite similar, wolves and dogs are also quite different.Wolves are wild animals that live in packs, or groups, and eat only meat. They find their food by hunting. The most common noise they make is a howl. They may also bark, growl, yelp, and whine. All wolves look very much alike, although their colors vary slightly. They are large, slender, powerful animals with long legs and tails. Wolves are quite wary of people; they dont trust them. They attack people only on rare occasions, usually when they are startled.A small dog is looking up at a large wolf.Dogs, on the other hand, are tame. They have been influenced by people for many, many years, which has made them quite different from wolves. For one thing, dogs eat vegetables and grains as well as meat products. They are much more likely to bark than to howl. Their sizes range from gigantic animals that are much larger than wolves to tiny animals that can sit comfortably in a cereal bowl. Large dogs are not only taller than wolves, but they are much heavier, and their appearances can vary as much as their sizes.However, the main difference is found in dogs relationship with humans, whom they usually prefer to be near. The main effect of this is that most dogs are friendly to people. Some show hostility, but almost always only to strangers. Although most dogs are no smarter than wolves, they can certainly be trained more easily. They rarely hunt prey to eat and depend on their owners to supply them with food. This reliance on people just adds to the closeness of the relationship.Wolves and dogs both pant to stay cool. They both can hear and smell very well, and they both can run silently. They even have the same number of teeth: 42. However, no matter how similar wolves and dogs may seem to be, wolves can never be made into a pet. They are also worthless as guard animals because they are shy. Domestic animals, such as cats and small dogs, are in more danger from wolves than humans are, but small children can also be in danger.
