line u - Line v, what is the value of x?

In the triangle  ΔJKL,  the length of side k found using the law of cosines is approximately 1764 inches.

What is meant by the law of cosines?

The law of cosines, commonly referred to as the cosine formula or cosine rule, is a relation in trigonometry that links the lengths of a triangle's sides to the cosine of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of the first two sides and the angle between them.

If ABC is a triangle, then as per the statement of cosine law,  we have:

c = [tex]\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]

where,

c = length of side c

a = length of side a

b = length of side b

γ = angle opposite c

Given a triangle, ΔJKL

The length of side l= 920 inches

The length of side j = 880 inches

∠K = 157°

According to the law of cosines,

k² = l² + j² - 2.l.j . cos K

  = 920² + 880² - 2 * 920 * 880  * cos (157°)

=  846400+ 774400 - (-1490481.46)

= 3111281.46

k = 1763.88 = 1764 inches.

Therefore the length of side k found using the law of cosines is approximately 1764 inches.

Answer:

Step-by-step explanation:

we can determine the maximum height using the expression given after finding the value of time at which the object reaches the maximum height. In order to find the time at which the object reaches the maximum height we need to use one of the UAM formulas.

and the compatible UAM formula is: vf=vi+at, we use UAM formula because the object is uniformly accelerating due to gravitational force.

vf=vi+at, at the point where the object reaches the maximum height its velocity will be zero so vf=0 and vi=29.4m/s.

given

a=-9.8m/s^2

vf=0

vi=29.4m/s

t=?

0=29.4-(9.8)t

-29.4= -9.8t

t= 29.4/9.8

t=3 seconds, it takes 3 seconds to reach the maximum height starting from a height of 30m.

h=30+29.4(3)-4.9(3)^2

h=30+88.2-44.1

h=118.2-44.1

h=74.1 m

The total number number of creamy peanut butter jars are 8556.

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

Given is that a factory made 9200 jars of peanut butter. 93% of the jars contained creamy peanut butter.

We can write the total number number of creamy peanut butter jars as -

{x} = 93% of 9200
{x} = 93/100 x 9200
{x} = 93 x 92
{x} = 8556

Therefore, the total number number of creamy peanut butter jars are 8556.

The name of the relationship is b. Alternate interior angles.

Alternate interior angles are two angles that are located on opposite sides of a transversal line, but within the same two lines. When two lines are cut by a transversal line, the alternate interior angles are always congruent, meaning that they have the same measure.

In this case, angles ∠1 and ∠4 are alternate interior angles. Alternate interior angles are formed when two parallel lines are cut by a transversal line. When this happens, corresponding angles are formed on the same side of the transversal.

The alternate interior angles are the two angles that are on opposite sides of the transversal. These angles are also congruent, meaning that they have the same measure.

The coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis include the following:

P" = (-4, 0).

Q" = (-(3), 1) = (-3, 1).

R" = (1, -2).

In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the coordinates of triangle P′Q′R′, the coordinates of triangle P′′Q′′R′′ include the following:

(x, y)                               →              (-x, y)

Coordinate P' = (4, 0)   →  Coordinate P" = (-(4), 0) = (-4, 0).

Answer:

the face value of the loan is $5,263.16.

Step-by-step explanation:

To determine the face value of the loan, we need to use the formula:

Face Value = Proceeds / (1 - Discount Rate * Time)

where "Time" is the time period of the loan in years.

Since the loan is for 6 months, we need to convert this time to years by dividing it by 12. Therefore, "Time" = 6/12 = 0.5 years.

Now, we can substitute the given values into the formula:

Face Value = 5,000 / (1 - 0.1 * 0.5)

Face Value = 5,000 / (1 - 0.05)

Face Value = 5,000 / 0.95

Face Value = $5,263.16 (rounded to the nearest cent)

Therefore, the face value of the loan is $5,263.16.

10x+3x+7x = 180 [ angle sum property of a triangle ]

20x = 180

x=180/20

Answer:

Step-by-step explanation:

Given: In triangle ABC, AB = AC and D is the midpoint of BC.

To prove:

i) AD is perpendicular to BC.

We can prove this by using the midpoint theorem, which states that a line segment connecting the midpoints of two sides of a triangle is perpendicular to the third side and half as long as the third side.

Since D is the midpoint of BC, we have BD = DC. Thus, the line segment AD connects the midpoints of sides AB and AC of triangle ABC.

By the midpoint theorem, AD is perpendicular to BC and AD = BC / 2.

ii) AD bisects angle BAC

We can prove this by using the fact that if two line segments are perpendicular and one is an altitude of a triangle, then the two line segments divide the triangle into four smaller triangles that are congruent by SAS congruence.

Since AD is perpendicular to BC, we have two right triangles, ABD and ACD. By the Pythagorean theorem, we have AB = AC, which means that ABD and ACD are congruent by SAS congruence.

Since ABD and ACD are congruent, we have angle BAD = angle CAD. Also, since angle BAC is the sum of angles BAD and CAD, we have angle BAC = 2 * angle BAD.

Therefore, by substitution, we have angle BAC = 2 * angle CAD. This means that angle CAD is half of angle BAC, or in other words, AD bisects angle BAC.

Hence, we have proved that in triangle ABC, AD is perpendicular to BC and AD bisects angle BAC.
