1.

1=87 corresponding angle.
2=180-87=93


2.

1=78 corresponding angles
2=78 verticle angles


3.

Set it up as (6x - 11) = 37
37 + 11 =48

6x = 48

x = 8


4.

Take 142 and see that it is supplementary to angle 2 so 180-142 = 38

38 is corresponding to the equation 2(x + 9)

So 2(x + 9) =38
Distributive property

2x + 18 = 38
38-18=20

2x =20

x = 10

Angle 2 is equal to 38 from supplementary to 142


I’m pretty positive about 1-3 but 4 maybe not be correct. But most likely these are correct

How much must be added to each of the three numbers 1, 11, and 23 so that together they form a geometric progression?
Sliva [168]

Answer:

49

Step-by-step explanation:

Let x be unknown number which should be added to numbers 1, 11, 23 to get geometric progression. Then numbers 1 + x, 11 + x, 23 + x are first three terms of geometric progression.

Hence,

b_1=1+x\\ \\b_2=11+x\\ \\b_3=23+x

and

b_2=b_1\cdot q\Rightarrow 11+x=(1+x)q\\ \\b_3=b_2\cdot q\Rightarrow 23+x=(11+x)q

Express q:

q=\dfrac{11+x}{1+x}=\dfrac{23+x}{11+x}

Solve this equation. Cross multiply:

(11+x)^2=(1+x)(23+x)\\ \\121+22x+x^2=23+x+23x+x^2\\ \\121+22x=23+24x\\ \\22x-24x=23-121\\ \\-2x=-98\\ \\2x=98\\ \\x=49
