The length of one leg of a right triangle is 3 feet more than the other leg. If the hypotenuse is 15 feet, find the length of ea
jeyben [28]

Answer:

9 and 12

Step-by-step explanation:

Pythagorean Theorem. One of the most common Pythagorean triples is 3, 4, 5 with 3 and 4 the legs and 5 the hypoenuse. That will make 9, 12, 15 anotther trible because you are tripling the side lengths. 12-9=3 so this triangle works.

when finding the distance between two rational numbers on a number line, does the order of the numbers you subtract matter?
sergeinik [125]

Answer:

the distance between two numbers and on the number line is . Note that the distance between two numbers is always positive, no matter the order. But the difference can be positive or negative, depending on the order.

Step-by-step explanation:

the distance between two points on a line is abs(x1-x2) which is a symmetric function abs(y)=abs(-y) so abs(x1-x2)=abs(-(x1-x2))=abs(x2-x1) so the order does not matter since you take abs after the subtraction.

hopes this helps

and mark me brainliest if it does

Need help! Law of cosines...find b round to the nearest tenth please
dusya [7]
ANSWER

B = 27.8 \degree

EXPLANATION

The law of cosine is given by the formula:

{b}^{2} = {a}^{2} + {c}^{2} - 2bc \cos(B)

From the diagram,

a=17, b=8, c=16

We substitute the given values into the formula to obtain:

{8}^{2} = {17}^{2} + {16}^{2} - 2(17)(16)\cos(B)

64 = 289+ 256- 544\cos(B)


64 = 545- 544\cos(B)


64 - 545 = - 544\cos(B)

- 481 = - 544\cos(B)

\frac{ - 481}{ - 544} = \cos(B)

cos(B) = 0.88419

B = \cos ^{ - 1} (0.88419)

B = 27.8 \degree
