pls help i don’t understand!
You may need to input the number only without the "degrees".
=============================================================
Explanation:
First we'll focus on triangle DEH. Ignore the other points and values.
We have the sides of EH = 32 and DH = 49. Let x be the measure of angle DHE, which is one of the pieces of angle DHG. We'll use the cosine rule to find x.
cos(angle) = adjacent/hypotenuse
cos(H) = EH/DH
cos(x) = 32/49
x = arccos(32/49)
x = 49.227195
The value is approximate and rounded to 6 decimal places. Make sure your calculator is in degree mode. Arccos is the same as inverse cosine.
We'll come back to this value later.
---------------------
Now focus on triangle HFG. Ignore the other points.
We have the sides of FG = 38 and GH = 43
Let y be the measure of angle FHG, which is the missing piece to form angle DHG. Based on how x and y are set up, we can say x+y = angle DHG.
To find y, we'll need the sine rule this time
sin(angle) = opposite/hypotenuse
sin(H) = FG/GH
sin(y) = 38/43
y = arcsin(38/43)
y = 62.094527 which is approximate to 6 decimal places
---------------------
The last step is to add the values of x and y we found earlier
angle DHG = (angle DHE) + (angle FHG)
angle DHG = (x) + (y)
angle DHG = (49.227195) + (62.094527)
angle DHG = 111.321722
angle DHG = 111 degrees after rounding to the nearest whole degree.
----------------------
If you wanted to do this all in one step, you could say:
arccos(32/49)+arcsin(38/43) = 111.3217 which rounds to 111 degrees.

Solve: 5(3x + 2) -2 = 2 (1 -7x)
Answer:
x=-6/29
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(3x+2)−2=2(1−7x)
(5)(3x)+(5)(2)+−2=(2)(1)+(2)(−7x)(Distribute)
15x+10+−2=2+−14x
(15x)+(10+−2)=−14x+2(Combine Like Terms)
15x+8=−14x+2
15x+8=−14x+2
Step 2: Add 14x to both sides.
15x+8+14x=−14x+2+14x
29x+8=2
Step 3: Subtract 8 from both sides.
29x+8−8=2−8
29x=−6
Step 4: Divide both sides by 29.
29x/29=-6/29
x=-6/29

Step-by-step explanation:
A wedding reception was
being held at Stefano's
restaurant. They charged
$2.00 per person for
appetizers, $20.00 per
person for the main course
and $250 for the wedding
cake. There were 50 people
at the reception. What was
the total cost of the
reception?
Answer:
the total cost of the wedding would be: 1,350
Step-by-step explanation:
2×50=100 and 20×50=1,000
100+1,000=1,100
1,100+ 250= 1,350
total for wedding is 1,350
:)
Answer: The answer for this problem is $1350.
Step-by-step explanation:
The first thing you do is to see how much money for the appetizers and the main course did all 50 people pay.
50 x 2 = 100, how much money in total for the appetizers
50 x 20 = 1000, how much money in total for the main course
Once you're done with that! Next, you add the total prices for the appetizers and the wedding cake. Then, you add up the $250, so you get your answer!
$100 + $1000 = $1100
$1100 + $250 = $1350
This is how you get the answer!

If the discriminant is equal to 4, how many solutions are there?
Answer:1 only solution
Step-by-step explanation:
If the discriminant is equal to 4, the number of solutions there are is; 2 solutions.
According to the question;
If the discriminant is equal to 4, how many solutions are there?When the discriminant is a perfect square as in 4 above; Then the solutions to the equation are not only real, but also rational.
However, If the discriminant is positive but not a perfect square, then the solutions to the equation are real but irrational.
There are 2 rational solutions if the discriminant is equal to 4.

Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125. Estimate the number of months that Zea can continue this pattern until she reaches her credit limit.
The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.
What is a credit card?A credit card is a method of payment that is given to customers so they may pay a merchant for products and services depending on the debt they have accumulated.
Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125.
The distinction between the installment made and the charges done will be given as,
Difference = $200 - $125
Difference = $75
Partition as far as possible by this distinction to find the number of months that Zea can proceed with this example until she contacts her credit limit.
⇒ $2,000 / $75
⇒ 26.667 ≈ 27
The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.

I have a question. It is: 5x+2y=4 3x+6y=-12 Solve the system of equations by graphing. How do I input that on a Casio graphing calculator. Giving brainliest if it works. Thanks!
Answer:
Step-by-step explanation:
[1] 5x + 2y = 4
[2] 3x + 6y = -12
Graphic Representation of the Equations :
2y + 5x = 4 6y + 3x = -12
// Solve equation [2] for the variable y
[2] 6y = -3x - 12
[2] y = -x/2 - 2
// Plug this in for variable y in equation [1]
[1] 5x + 2•(-x /2-2) = 4
[1] 4x = 8
// Solve equation [1] for the variable x
[1] 4x = 8
[1] x = 2
// By now we know this much :
x = 2
y = -x/2-2
// Use the x value to solve for y
y = -(/2)(2)-2 = -3
