Answer 1

use angle addition postulate:

---

1) angle (2x+10) and (x+5) are supplementary, meaning they add up to 180 degrees so

(2x+10)+(x+5)=180

3x+15=180

x=55

---

2) angle (x-30) and x are complementary, meaning they add up to 90 degrees

(x-30)+x=90

2x-30=90

x=60

Answer 2
problem one
x = 55

problem two
x = 60

A tank is being filled with water at a rate of 5.5 gallons per
minute. Write the first five terms of the arithmetic sequence
being represented after each minute if the tank started with
10 gallons of water.

Answers

Arithmetic sqaure: a + (n-1) * d

              where "a" is the first term, "d" is the common difference

Here given:

a = 10 gallons

d = 5.5 gallons

nth term: 10 + (n-1) * 5.5

Solve for first 5 terms:

10 + (1-1) * 5.5 = 10

10 + (2-1) * 5.5 = 15.5

10 + (3-1) * 5.5 = 21

10 + (4-1) * 5.5 = 26.5

10 + (5-1) * 5.5 = 32

first five terms: 10, 15.5, 21, 26.5, 32

First term=a=10common difference a=5.5

General formula

a_n=a+(n-1)da_n=10+(n-1)5.5

So

a_1=10a_2=10+5.5=15.5a_3=10+11=21a_4=10+16.5=26.5a_5=10+22=32a_6=10+27.5=37.5

Answers

Answer:

a = 39.2650873379cm

b = 11.5529459767cm

Step-by-step explanation:

a - Use the area of a triangle equation -  1/2 * a * b * Sin(C)

1/2 * 8 * 10 * Sin(79) = 39.2650873379cm

b - Use the cosine rule - c^2 = a^2 + b^2 - (2 * a * b * Sin(C)

64 + 100 - (2 * 8 * 10 * Cos(79)) = 133.4705607398

c = square root of 6.9396506484 = 11.5529459767cm

Which inequality best represents the phrase?

A number less then 0

A. n=0
B. n greater than n 0
C. n greater then n with a underscore on the bottom 0
D. n greater than 0 with a underscore 0​

Answers

Im not sure what it is but my best bet would be on A because the rest of them all say greater than 0 and you are trying to find the least.

Answer:

n < 0

Step-by-step explanation:

Given that:

A number less than 0

Solve:
Since it saying that A number (n) is less than 0 it means it can't be greater.

From the following answer chioce:

[A] n=0

[B] n greater than n 0

[C] n greater then n with a underscore on the bottom 0

[D] n greater than 0 with a underscore 0​

We can see that [B], [C], and [D] all saying greater than. While only [A] has a equal sign to 0.

I'm guess that [A] meant to be put as n < 0. Since the other are saying greater than. But if not. None of the above are correct.

< → less than

> → greater than

A number less than 0 ⇒ n < 0

4 = x^3
x = ∛4

x = 1.587

Using the pythagoras theorem;

how to complete the square?

Answers

Answer:

x = 12 and x = -6

Step-by-step explanation:

First subtract 6x on both sides to get a 2nd degree polynomial equal to zero:

[tex]x^2-6x-72=0[/tex]

To complete the square, the formula is to divide 'b' by 2 and square the result. The general form for a 2nd degree polynomial of the variable 'x' is as follows:

[tex]ax^2+bx+c=0[/tex]

For your case, b = 6. Therefore, the term that must be added and subtracted to our equation is:

[tex](6/2)^2=3^2=9[/tex]

Add and subtract 9 to our equation to get:

[tex]x^2-6x+9-9-72=0[/tex]

The first three terms form a perfect square, we have:

[tex](x^2-6x+9)-9-72=0[/tex]

[tex](x^2-6x+9)-81=0[/tex]

What multiplies to equal 9 but adds to equal -6? That would be -3 and -3. Therefore:

[tex](x-3)^2-81=0[/tex]

Add 81 to both sides to get:

[tex](x-3)^2=81[/tex]

We want to take the square root, but recall a square root has a positive and negative branch. Therefore we have two solutions:

[tex]x-3=9[/tex]

[tex]x-3=-9[/tex]

[tex]x=12[/tex]

[tex]x=-6[/tex]

Answer:

Step-by-step explanation
x^2-6×-72= O
(b/2)^2= b, -6:(-6/2)^2=(-3)^2= 9
x^2-6x+(-3)^2-(-3)^2-72=0
(x-3)^2-9-72=0
(x-3)^2-81= 0
(x -3)^2= 81, x-3= ±9
x= +9+3= 12
x= -9+3=-6
: X= 12 , X= -6

Answers

The height of the tree that forms an angle of 64 degrees and point from the tree is 49 feet is 100.46 ft

The situation forms a right angle triangle.

How to find the sides when given angle of elevation

using trigonometric ratios,

tan 64 = opposite / adjacent

Where

opposite side = height of the treeadjacent side = distance from the point on the ground from the tree.

Therefore,

tan 64 = h / 49

cross multiply

h = 49 × tan 64

h = 49 × 2.05030384158

h = 100.464888237
