Answer:

x = 4

m∠EFH = 21°

m∠EFG = 83°

Step-by-step explanation:

We know that m∠EFH + m∠HFG will be equal to m∠EFG.

Since we know the values of each, we can make the equation:

5x + 1 + 62 = 18x + 11

Let's solve for x by isolating it on one side.

Combine like terms:

5x + 63 = 18x + 11

Subtract 11 from both sides:

5x + 52 = 18x

Subtract 5x from both sides:

52 = 13x

Divide both sides by 13:

x = 4

Now that we know the value of x, we can substitute it inside the formulas for m∠EFH and m∠EFG.

m∠EFH:

5x+1\\\\5(4)+1\\\\20+1\\\\21

m∠EFG:

18x+11\\\\18(4)+11\\\\72+11\\\\83

Hope this helped!

What is the next fraction in each of the following patterns?1/40,4/40,9/40,16/40,25/40...?
tresset_1 [31]
Let
a1=1/40
a2=4/40
a3=9/40
a4=16/40
a5=25/40
a6=?

we know that
a2-a1=4/40-1/40----> 3/40
a3-a2=9/40-4/40-----> 5/40
a4-a3=16/40-9/40----> 7/40
a5-a4=25/40-16/40---> 9/40

the difference is
3/40,5/40,7/40.9/40,....
3/40+[2/40]---> 5/40
5/40+[2/40]---> 7/40
7/40+[2/40]---> 9/40

the next will be
9/40+[2/40]-----> 11/40
so
the next term is 25/40+[11/40]------> 36/40

the answer is
36/40

Select the correct answer.
masya89 [10]

Answer:

D

Step-by-step explanation:

Either try all the numbers and see which ones work or do the following.

Times both sides by 2x-5.

3=x(2x-5)=2x^2-5x

Rearrange and solve the quadratic. I will factorise.

2x^2-5x-3=0

(2x+1)(x-3)=0

so x = -1/2 or 3
