Answer:

The measure of the indicated angle is 72°

Step-by-step explanation:

If two parallel lines intersected by a transversal, then

There are pairs of corresponding angles equal in measures

There are pairs of alternate interior angles equal in measures

There are pairs of alternate exterior angles equal in measures

There are pairs of adjacent interior angles that are supplementary

In the given figure

∵ There are two parallel lines intersected by a transversal

∵ The angle of measure 108° and the indicated angle are adjacent

interior angles

∴ They are supplementary

∵ The sum of the measures of supplementary angles is 180°

∴ 108 + indicated angle = 180

→ Subtract 108 from both sides

∴ The measure of the indicated angle = 72°

An arithmetic sequence is represented in the following table. Enter the

pentagon [3]

Answer:

122

Step-by-step explanation:

An arithmetic sequence means a number is added each term. There is a term for where a number is multiplied as well. But in this case the first number is -103, the second number is -94 and the third number is -85. Can you tell what number is added each time?

The number is 9. -103+9=-94 and -94+9=-85 and so on. Now we want a way to find the term way further down the line.

Think of it doing it all at once. -103+9+9 gets us the third term right? so that's 2*9. -103+3*9 would get us the fourth. Hopefully that makes sense, but let me know if it doesn't. But for a few more examples, if we want the fifth term we would do -103+4*9 and getting the tenth would need -103+9*9. So basically we take the number term we want (in this case we want the 26th) and then take -103+ n*9, where n is the term we want minus 1, or in this case 25. so that's -103+25*9

Let me know if you need more of an explanation.

Create at least 3 subtraction problems that have a common denominator of 20 using the fractions one sixth two fifths four sevent

Umnica [9.8K]

Answer:

1. 1/2-2/5

2. 3/4-2/5

3. 1/2-3/4

Step-by-step explanation:

For you to be able to create such fractions you must make sure that the numerator is divisible by 20.

Clearly the number 2,4 and 5 can divide 20.so therefore any fraction formed with them will give the denominator 20
