Answer:

The answer in the procedure

Step-by-step explanation:

Part A)

we know that

The measures of interior angle in a triangle must be equal to 180 degrees

In the triangle AUL

m>3+25\°+52\°=180\°

m>3=103\°

m -----> by supplementary angles

m

m

The sum of the two nonadjacent interior angles is equal to

25\°+52\°=77\°

therefore

m<4 is equal to the two nonadjacent interior angles

Part B) m ----> see the Part A)

A cuboid with a volume of 924 cm^3 has dimensions
eduard

Answer:

21

Step-by-step explanation:

Volume of a cuboid is given by

V = l*w*h

924 = 4 (x+1) (x+11)

FOIL

924 = 4(x^2 +11x+x+11)

924 = 4(x^2+12x+11)

Divide each side by 4

231 = (x^2+12x+11)

Subtract 231 from each side

0 = x^2 +12x +11-231

0 = x^2 +12x - 220

Factor

0 = (x+22) (x-10)

Using the zero product property

x+22 =0  x-10 =0

x=-22  x=10

We cannot have a negative length

x=10

The side lengths are 4, 10+1, 10+11

4,11,21

The longest is 21

Solve algebraically:

<h3>Answer:</h3>

a)\ x_1=-9,\ x_2=9\\\\b)\ x_1=1,\ x_2=5

<h3>Step-by-step explanation:</h3>

<u>Given equations:</u>

a)\ 2x^2 - 162 = 0\\\\b) -\dfrac{1}{2}(x-3)^2=-2

A) 2x² - 162 = 0

Step 1: Divide both sides by 2.

<h3>\\\implies \dfrac{2x^2 - 162}{2} = \dfrac{0}{2}\\\\\implies x^2-81=0\\\\\implies x^2=81</h3>

Step 2: Take the square root of both sides (using both the positive and negative roots).

\\\implies \sqrt{x^2}=\sqrt{81}\\\\\implies x=\pm\ 9

Step 3: Separate into two cases.

\implies x_1 = -9,\ x_2 =-9

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

B) -1/2(x - 3)² = -2

Step 1: Multiply both sides by -2.

\\\implies -2\left(-\dfrac{1}{2}(x-3)^2\right)=-2(-2)\\\\\implies (x-3)^2=4

Step 2: Take the square root of both sides (using both the positive and negative roots).

\\\implies\sqrt{(x-3)^2}=\sqrt{4}\\\\\implies x-3=\pm\ 2

Step 3: Separate into two cases and solve each one.1)\ x-3=-2\implies x=-2+3\implies \boxed{x=1}\\\\2)\ x-3=2\implies x=2+3\implies \boxed{x=5}
