In ΔJKL, k = 430 cm, l = 590 cm and ∠J=117°. Find the length of j, to the nearest centimeter.
Answers
Answer:
874
Step-by-step explanation:
The length of j from the given triangle JKL is 550 cm.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔJKL, k = 430 cm, l = 590 cm and ∠J=117°.
Using cosine rule
j²=k²+l²-2kl.cosJ
j²=430²+590²-2×430×590·cos117°
j²=184900+348100-507400×0.4539
j²=533000-230308.86
j²=302691.14
j=√302691.14
j=550 cm
Therefore, the length of j from the given triangle JKL is 550 cm.

the sum of the angles in a triangle add up to equal 180
180-73-13=94
Answer: X = 89°
Step-by-step explanation:
At first glance I could tell this was an isosceles triangle, the angles of an isosceles triangle add up to 180°. So just add 73° + 13° = 91° so then you subtract 91° from 180° and you get 89°.

Express the number of months in the year that are only 4 letters as a fraction in the simplest form, decimal rounded to the nearest thousandth and whole percent.
Answers
Answer:
There are only 2 months out of the 12 that have 4 letters in their name so it would be represented as 2/12, the numerator representing those 2 months and the numerator representing the 12 months in 1 year. 2/12 in its simplest form would be 1/6 because if you use the big one to simplify 2/12 and divided it by 2/2 you get 1/6. 1/6 as a decimal is 0.16 wich is 16% as a percent.

what is the value of p so that the expession 6x+3-(8x-5) is equivalent to (px+8)?
Answers
Answer:
-2
Step-by-step explanation:
The first equation simplifies to -2x+8 so p should be replaced with -2
The value of p so that the expression 6x+3-(8x-5) is equivalent to (px+8) is, -2
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
An expression, 6x+3-(8x-5)
another expression, (px+8)
Value of p for which both the expressions are equivalent = ?
So now, we can compare both the expressions
⇒ 6x+3-(8x-5)
⇒ 6x+3-8x+5
⇒ -2x+8
if compare it with (px+8)
then, p = -2
Hence, the values of p is -2

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
What is LCM?It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
The GCF of 14x and 18xy
As we know, GCF is the greatest common factor.
The greatest common factor of 14 and 18 or
GCF(14, 18) = 2
And the greatest common factor of GCF of x and xy
= x
the greatest common factor of 14x and 18xy is:
= 2x
Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

A triangle is dilated with a center of dilation at the origin. Point P is on the figure and P' is the corresponding point on the image of the dilation. Point P is at (-2, 3) and P' is at (-8, 12). Which rule best represents the dilation? *
Answers
Answer:
(x, y) → (4x, 4y)Step-by-step explanation:
Dilation is applied by the rule:
(x, y) → (kx, ky), where k is the scale factorWe have
(x, y) = (-2, 3) and (kx, ky) = (-8, 12)Substitute and solve for k
-8 = -2k and 12 = 3k ⇒ k = 4So the rule is
