Answer:

36, 32, 28, 24

Step-by-step explanation:

Fill in the values of n and do the arithmetic.

a1 = 36 -4(1 -1) = 36

a2 = 36 -4(2 -1) = 32

a3 = 36 -4(3 -1) = 28

a4 = 36 -4(4 -1) = 24

_____

You could recognize the formula as the specific case of the explicit formula for an arithmetic sequence with first term 36 and common difference -4. That tells you the second term is 36 -4 = 32, and each successive term is 4 less than the one before.

Tell whether the angles are adjacent or vertical. Then find the value of x. (Only 4-6)

eduard

Alright, lets get started.

If two angles have common side and they shares common vertex, they are called adjacent angles.

When two lines crosses each other, the opposite angles are called vertical angles as they share same vertex.

Question 4:

Two angles shown in diagram are adjacent as they are on common side.

Both the angles are on a straight line, hence

$x + 109 = 180$

Subtracting 109 from both sides

$x + 109 - 109 = 180 - 109$

$x = 71$ ° : Answer

Question 5:

Both angles shown in diagram are opposite to each other, hence vertical angles.

As they are opposite to each other, they both are equal.

$x+42= 2x + 1$

Subtracting x from both sides

$x + 42 - x = 2x + 1 - x$

$42 = x + 1$

Subtracting 1 from both sides

$42 - 1 = x + 1 - 1$

$x = 41$ ° : Answer

Question 6:

Both angles are having a common side means they are adjacent angles.

As they are on straight line, both angles will add up to 180 °.

$x+96 + 5x = 180$

$6 x + 96 = 180$

Subtracting 96 from both sides

$6x + 96 - 96 = 180 - 96$

$6x= 84$

Dividing from 6 in both sides

$\frac{6x}{6} =\frac{84}{6}$

$x = 14$ ° : Answer

Hope it will help :)

Does anyone know this?

Answer:

66 degrees

Step-by-step explanation:

assuming that the line RN crosses line QO in the mid point, and that from that point to R, and to N, are the same length, then the angles R and N should be the same making angle O the complimentary angle, that would be 66 degrees

170+ 35 - 5 = 2s + 25

Len [333]

Answer:

s = 87.5

Step-by-step explanation:

We start with 170 + 35 - 5 = 2s + 25

We want to find the value of s. Since one side of the expression (170 + 35 - 5) isn't simplified yet, that's what we should start with.

Evaluate: 170+ 35 - 5

170 + 35 - 5 = 200

Now our equation is 200 = 2s + 25

Solve using algebraic methods:

Start by subtracting 25 from both sides of the equation to get:

175 = 2s

Then, divide both sides by 2:

87.5 = s

The final answer you get should be s = 87.5

Hope this helps!
