Answer:

113\° = \angle A

Step-by-step explanation:

Given:

  • ∠A = ∠B (Vertically opposite angles)
  • ∠A = 7x - 20
  • ∠B = 6x - 1

If ∠A is equivalent to ∠B, then...

\implies 7x - 20 = 6x - 1

Add 1 both sides:

\implies 7x - 20 + 1= 6x - 1 + 1

Simplify both sides:

\implies 7x - 19= 6x

Subtract 7x both sides:

\implies 7x- 7x  - 19= 6x - 7x

Simplify both sides:

\implies -19= -x

Divide both sides by -1:

\implies \dfrac{-19}{-1} = \dfrac{-x}{-1}

Simplify both sides:

\implies 19= x

Substitute the value of x into "7x - 20" to determine ∠A:

\implies 7x - 20 = \angle A

\implies 7(19) - 20 = \angle A

Simplify the expression:

\implies 133 - 20 = \angle A

\implies 113\° = \angle A

Answer:

∠ A = 133

Step-by-step explanation:

Putting both angels together

Since,

m ∠ A = (7x-20)

m ∠ B = (6x-1)

Thus,

(7x-20) = (6x-1)

Solving for x:

7x  - 20 = 6x -1

  +20           +20

-------------------------

7x =  6x + 19

-6x    -6x  

-----------------------

1x = 19  

x = 19

7(19) -20 =  113

6(19) - 1 = 113  

Hence measure of m ∠ A = 113

What is the lateral surface area of the pyramid?
Delicious77 [7]

Answer:

1,536 square centimeters

Step-by-step explanation:

The formula for the Lateral surface area of the pyramid =

1/2 × perimeter of the square base × slant height

Square base = 32cm

Slant height = 24cm

Perimeter of the square base = (4 × length of the square base side)

4 × 32cm = 128cm

Lateral Surface Area = 1/2 × 128cm × 24cm

= 1,536 square centimeters

4. Match the polynomial in the left column with its descriptive feature in the
FromTheMoon [43]

Complete question is;

Match the polynomial in the left column with its descriptive feature in the

right column

A.) x³ + 3x² - 2x + 7

B.) 3a³ b ^(6)

C.) 3x⁴ – 9x³ + 5x^(8)

D.) 7a³ b ² + 18ab² c – 9a³

E.) 2x^(5) – 9x³ + 8x^(7)

F.) 4x^(8) – 7x² + 9

G.) x² − 7

I. 9th degree monomial

II. Constant term of −7

III. 7th degree polynomial

IV. Leading coefficient of 4

V. Four terms

VI. 5th degree polynomial

VII. Equivalent to 5x^(8) + 3x⁴ – 9x³

Answer:

A) For polynomial x³ + 3x² - 2x + 7 : Option V - 4 Terms

B) For polynomial 3a³ b ^(6) : option I - 9th degree monomial

C) For the polynomial 3x⁴ – 9x³ + 5x^(8) : Option VII - Equivalent to 5x^(8) + 3x⁴ – 9x³

D) For the polynomial 7a³b² + 18ab²

c – 9a³ : Option VI - 5th degree polynomial.

E) For the polynomial 2x^(5) – 9x³ + 8x^(7) : Option III - 7th degree polynomial.

F) for the polynomial 4x^(8) – 7x² + 9 : Option IV - Leading coefficient of 4

F) For the polynomial x² − 7 : Option II - Constant term of −7

Step-by-step explanation:

A) Most appropriate matching descriptive feature for the polynomial x³ + 3x² - 2x + 7 is Option V - 4 Terms

B) Most appropriate matching descriptive feature for the polynomial 3a³ b ^(6) is option I - 9th degree monomial. This is because the sum of the powers of a and b is 9.

C) Most appropriate matching descriptive feature for the polynomial 3x⁴ – 9x³ + 5x^(8) is Option VII - Equivalent to 5x^(8) + 3x⁴ – 9x³

D) Most appropriate matching descriptive feature for the polynomial 7a³ b ² + 18ab² c – 9a³ is Option VI - 5th degree polynomial. This is because the highest sum of powers attached to a and b in a figure is 2 + 3 = 5.

E) Most appropriate matching descriptive feature for the polynomial 2x^(5) – 9x³ + 8x^(7) is Option III - 7th degree polynomial. This is because the highest power of x is 7.

F) Most appropriate matching descriptive feature for the polynomial 4x^(8) – 7x² + 9 is Option IV: Leading coefficient of 4. This is because the coefficient attached to the largest power of x is 4.

G) Most appropriate matching descriptive feature for the polynomial

x² − 7 is Option II - Constant term of −7

-12 is greater than or equal to 24x solve
geniusboy [140]
Well this depends a lot about what your variable represents in this problem since if you have like -12 is greater than 24(-5). So it really just depends on your variable but if it's just -12 and 24 then 24 is greater than -12. So -12 is less than 24.
