The angle measurements in the diagram are represented by the following expressions.
Aleonysh [2.5K]

Answer:

x = 6

∠B = 126

Step-by-step explanation:

∠A = ∠B through alternate interior angles

∠A = ∠B

8x + 78 = 2x + 114

8x - 2x = 114 - 78

6x = 36

x = 36 ÷ 6

x = 6

∠B = 2x + 114

2(6) + 114

12 + 114

= 126

How do you find the first five terms of a sequence defined recursively
Blizzard [7]
Interesting question. Good to know for computer science.
Suppose you have a function like 
an = 3x - 2 Try the first couple
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1

a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4 So each term differs by 3
a2 - a1 = 3

an = a_(n - 1) + 3
a3 = a2 + 3
a3 = 4 + 3 
a3 = 7

a4 = a3 + 3
a4 = 7 + 3
a4 = 10

a5 = a4+ 3
a5 = 10 + 3
a5 = 13

I'll do one more and then check it.
a6 = a5 + 3
a6 = 13 + 3
a6 = 16

a6 = 3x -2
a6 = 3*6 - 2
a6 = 18 - 2
a6 = 16 which checks.

So the general formula is
an = a_(n - 1) * k if you were multiplying or
an = a_(n - 1) + k if you were adding. The key thing is that you are working with the previous term.

Len [333]

Answer:

A. g=11

Step-by-step explanation:

We want to find which choice makes the equation true. Let's plug in each answer choice.

A. g=11

26=7(11-9)+12      

26= 7(2)+12              Solve inside the parentheses.

26= 14+12                 Multiply 7 and 2.

26= 26                      Add 14 and 12.

This answer must be correct, but let's check the other choices .

B. g=12

26=7(12-9)+12      

26= 7(3)+12              Solve inside the parentheses.

26= 21+12                 Multiply 7 and 3.

26≠33                       Add 14 and 12.

This choice is not correct.

C. g= 13

26=7(13-9)+12      

26= 7(4)+12              Solve inside the parentheses.

26= 28+12                Multiply 7 and 4.

26≠40                      Add 28 and 12.

This is also not correct.

D. g= 14

26=7(14-9)+12      

26= 7(5)+12              Solve inside the parentheses.

26= 35+12                 Multiply 7 and 5.

26≠47                       Add 35 and 12.

This choice is not correct either.

The value of g that make the expression 26=7(g-9)+12 a true statement is A. g=11.

Plz help i don’t understand this type of math
Serga [27]
QRS = DRS + QRD
167 = x + 143 + x + 30
167 = 2x + 173
-2x = 173 - 167
-2x = 6
x = 6/-2
x = -3

DRS = x + 143
= (-3) + 143
= 140
