How do you find x? Please help
joja [24]
ANSWER:

x = 5

The value of ( x ) is equivalent to 5.

STEP-BY-STEP EXPLANATION:

Testing triangle AHD is congruent to triangle CHD -

Angle ADH = Angle CDH ( given )

Side AH = Side CH ( given )

Angle AHD = Angle BHC = 90° ( equal vertically opposite angles )

Angle CHD = 180° - Angle AHD = 180° - 90° = 90° ( supplementary angles on a straight line )

Angle AHD = Angle CHD = 90°

Angle DAH = Angle DCH ( angle sum of a triangle )

Therefore, triangle AHD is congruent to triangle CHD.

As triangle AHD is congruent to triangle CHD, we can do the following:

AD = 2x - 3

CD = x + 2

AD = CD

THEREFORE:

2x - 3 = x + 2

2x - x = 2 + 3

x = 5

3. Given: Circle Q<br>&lt;A = 35<br>Find: m AB​
Agata [3.3K]

Answer:  110°

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

∠A ≅ ∠B  

since ∠A = 35° (given), then ∠B = 35°

Use the Triangle Sum Theorem to find ∠C:

∠A + ∠B + ∠Q = 180°

35° + 35° + ∠Q = 180°

     70°    + ∠Q = 180°

                 ∠Q = 110°

The central angle (∠AQB) ≅ arc AB

since ∠AQB = 110° (solved above), then arc AB = 110°

A printer has a contract to print 100,000 posters for a political candidate. He can run the posters by using any number of plate
yulyashka [42]

Answer:

25

Step-by-step explanation:

From the given information;

Numbers of posters that can be printed in an hour = no of impression/hour × no of plate utilized in each impression.

= 1000x

Thus, the required number of hours it will take can be computed as:

\implies \dfrac{100000}{1000x} \\ \\ =\dfrac{100}{x}

cost per hour = 125

If each plate costs $20 to make, then the total number of plate will equal to 40x

∴

The total cost can be computed as:

C(x) = (\dfrac{100}{x}) \times 125 + 20 x --- (1)

C'(x) = (-\dfrac{12500}{x^2})  + 20  --- (2)

At C'(x) = 0

\dfrac{12500}{x^2} = 20

\dfrac{12500}{20} = x^2

x^2= 625

x = \sqrt{625}

x = 25

C'' (x) = -12500 \times \dfrac{-2}{x^3} +0

C'' (x) = \dfrac{25000}{x^3}

where; x = 25

C'' (x) = \dfrac{25000}{25^3}

C''(x) = 1.6

Thus, at x = 25, C'' > 0

As such, to minimize the cost, the printer needs to make 25 metal plates.
