Answer:

x=61°

Step-by-step explanation:

We can see that angle 2x-6 has a corresponding angle above it, which is congruent. That angle is supplementary with angle x+3, meaning that their sum is 180°. We can tell because they form a straight line/straight angle.

So,

(2x-6)+(x+3)=180

2x-6+x+3=180

3x-3=180

3x=183

x=61

Answer:

Step-by-step explanation:

Recursive sequences generally look like this:

a1 = something

an= ahhhhhh

The 1st term in this sequence is 11.

So we have

a1=11

And now we see that each term is adding by 22.

We have,

a1=11

[tex]a_{n} =a_{n-1}+22[/tex]

Answer:

2^4=16

Answer: 5 5/7

Step-by-step explanation:

Number of pizza bought = 20

Fraction of pizza ate = 2/7

Therefore, the number of pizzas that have been eaten will be:

= Fraction of pizza eaten × Number of pizza bought

= 2/7 × 20

= 40/7

= 5 5/7

Therefore, 5 5/7 pizza have been eaten

Answer:

measure of angle 5 = 75 degrees

Step-by-step explanation:

given measure of angle 8 = 105 degrees,

angle 8 and angle 5 are in a linear pair so,

(the sum of angles in a linear pair is 180 degrees)

therefore, angle 8 + angle 5 = 180 degrees

therefore,. 105 + angle 5 = 180 degrees

angle 5 = 180 - 105

angle 5 = 75 degrees

Answer:

20

Step-by-step explanation:

First step is finding an angle in the rightmost triangle (angle K)

Using TOA we have

Tan(x)=4/8

x=26.565

which means that 90-26.565= 63.4349 will give us angle K in regards to the left triangle

Using this we can solve for JM

Tan(63.4349)=x/8

8tan(63.4349=x

x=16

So if JM = 16

and LM=4

take their sum to find JL

16+4=20

Answer:

[tex]84^{\circ}[/tex]

Step-by-step explanation:

The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:

[tex]2(7x-7)=9x+21[/tex]

Solving, we get:

[tex]2(7x-7)=9x+21,\\14x-14=9x+21,\\5x=35,\\x=7[/tex]

Plugging in [tex]x=7[/tex] into [tex]9x+21[/tex]:

[tex]\widehat{DG}=9(7)+21,\\\widehat{DG}=63+21,\\\widehat{DG}=\boxed{84^{\circ}}[/tex]

Answer:

x=-3.7

Step-by-step explanation:

Answer:If the triangles are similar, the ratio of corresponding sides will be equal.

AC / DF = BC / EF

Substitute their values,

12 / 10 = 18 / EF

EF = 18/12 * 10

EF = 3/2 * 10

EF = 30/2

EF = 15 cm

In short, Your Answer would be 15 cm

Answer:

For 1, you'd have 14, 7, 0, -7

Step-by-step explanation:

Remember arithmetic sequences are adding the same thing (the difference) over and over and over. So in this case, you have the following:

1st blank: 14 + d

2nd blank: 1st blank + d OR (14 + d) + d = 14 + 2d

the -7 then is the 2nd blank + x OR [(14 + d) + d] + d

So you are adding 3d to the 14 to get to the -7. Set that up as the equation:

14 + 3d = -7.

When you solve for d, you get -7. That's what you'll add to 14 to get the first number, then add it again to get the second, etc.

The coefficient in front of d will always be one more than the number of spaces since you are adding the difference to find each blank IN ADDITION TO the last number in the sequence. So #4 would be setup like this:

2 + 5d = 57

Good luck!
