Answer 1

Answer:

15

Step-by-step explanation:

I forgot all of my math vocab but basically because the two lines are parallel, those two angles are equal to each other, so 4x-30=2x

subtract 2x from both sides so that 2x-30=0

Now add 30 to both sides

2x=30

divide both sides by two

x=15

find MK​

Answers

Answer:

MK=32.5

Step-by-step explanation:

Hey There!

I believe that these triangles are similar

So to find MK we want to find the scale factor

To do this we divide

66/30=2.2

Now we want to divide 72.5 by 2.2

72.5/2.2=32.5

therefore MK=32.5

hope this helps!

In ΔIJK, k = 64 inches, j = 17 inches and ∠J=68°. Find all possible values of ∠K, to the nearest 10th of a degree.

Answers

Answer:

N/A  (if on delta math leave blank)

Step-by-step explanation:

(3.4905745)=ERROR

Sine cannot be greater than 1.

The given conditions cannot form a triangle, there is no possible value of K.

What is sine law?

In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

Given that, in a triangle Δ IJK, k = 64 inches, j = 17 inches and ∠J = 68°.

We need to find value of ∠K,

So, using the sine law,

Sin K / k = Sin J / j = Sin I /i

So,

Sin K / k = Sin J / j

Sin K / 64 = Sin 68° / 17

Sin K = 3.5

K = Sin⁻¹(3.5)

K = ERROR

Hence, the given conditions cannot form a triangle, there is no possible value of K.

One day 197 Eagle Ridge students went on a field trip. Five busses were filled with the same number of students, and two students traveled separately by car. How many students were on each bus?

Answers

Answer: 39 students

Step-by-step explanation:

First, remove the number of students who traveled by car from the total number so we can see the number of students who traveled by bus:

= 197 - 2

= 195 students by bus.

These 195 students traveled in 5 buses. The number of students on each bus is therefore:

= No. of students traveling by bus / No. of buses

= 195 / 5

= 39 students

Find the value of x.

Answers

Answer:

x = 30.74

Step-by-step explanation:

39 - 15 = 24

y^2 + 24^2= 36^2

y^2 + 576= 1296

y^2= 720

y= [tex]12\sqrt{5}[/tex]

15^2 + [tex]12\sqrt{5} ^{2}[/tex]= x^2

225 + 720 = x^2

x^2= 945

x = 30.74

the value of x=30.74

10. The sum of a certain number and a second number is -42. The first
number minus the second number is 52. Find the numbers.
56​

Answers

Answer:

the first number and the second number is 5 and -47 respectively

Step-by-step explanation:

Let us assume the first number be x

And, the second number be y

According to the question

x + y = -42

x - y = 52

x = 52 + y

Now put the value of x in the first equation  i.e.

x + y = -42

52 + y + y = -42

2y = -42 - 52

2y = -94

y = -47

And, x is

x + y = -42

x -47 = -42

x = 5

Hence, the first number and the second number is 5 and -47 respectively
