Angles on a straight line add up to 180° so all you have to do is:

180 - 75 = 105

So CFD = 105°

Answer:

The Value of Angle CFD is 105°

Step-by-step explanation:

As you mentioned in the question, Triangle DEF is an isosceles triangle so angles DEF and DFE have the same degree value. If Angle DEF measures 75° then Angle DFE measures 75° as well.

A straight line has an Angle of 180°. Seeing as how CFE is a straight line and Angle DFE is 75°. We can subtract 75° from 180° in order to get the Angle CFD.

$180-75 = 105$

So the Value of Angle CFD is 105°

Solve this equation 4m+2=18

denis23 [38]

Hello there!

4m + 2 = 18

First, we need to isolate 4m and then solve for m.

4m + 2 = 18

Subtract 2 from both sides.

4m = 16

Divide both sides by 4 to solve for m.

m = 4

Which sum does not equal ?<br> 7/8

Drupady [299]

The sum which is not equal to 7/8 is 7/8 +7/8 = 14/8

Given,

a) 2/8 + 5/8 = 7/8 which is equal to 7/8.

Therefore, option a) is incorrect.

b) 1/8 + 6/8 = 7/8, which is also equal to 7/8.

Option b) is also incorrect.

c) 7/8 + 7/8 = 14/8 , which is not equal to 7/8.

Hence option c) is correct.

d) 3/8 + 4/8 = 7/8, which is equal to 7/8.

Option d) is also incorrect.

Hence option c) is correct as it matches the conditions of the question.

7/8 + 7/8 = 14/8 is not equal to 7/8.

Generalize the pattern by finding the nth term.

Veseljchak [2.6K]

Answer:

4n+2

Step-by-step explanation:

The common difference between the terms is 4 which means that the sequence is an arithmetic sequence.

The general formula for arithmetic sequence is:

$a_{n}=a_{0}+(n-1)d$

where a_n is the nth term, a_0 is the first term and d is the common difference between them.

We know that

$a_{0}=6\\d=4$

Putting the value in general formula:

$a_{n}=6+4(n-1)\\a_{n}=6+4n-4\\a_{n}=4n+6-4\\a_{n}=4n+2\\$

So the generalized pattern is 4n+2 ..
