Answer:

x = 36°

Step-by-step explanation:

There are 180° on a line so 180° - 126° = 54°

54° is one of the angles and so is 90° (because it is a right angle)

Therefore, now we know that x = 180° - (54° + 90°)

54° + 90° = 144°

180° - 144° = 36°

x = 36°

Answer:

x = 36

Step-by-step explanation:

solution:

we have given,

            in the right angled triangle.

             exterior angle = 126^{o}

we know,

          exterior angle = sum of interior non adjacent angle

   so,   126^o = x + 90^o    [∵ one angle of right angled triangle is 90^o]

     or,  x = 126^o - 90^o\\

     or,  x = 36^o

hence, the value of x is 36^o

Find the value of X, then find AB and DC.
zhannawk [14.2K]

Answer:

X=2, AB=14, DC=14

Step-by-step explanation:

3x+8=x+12

Subtract x from both sides

2x+8=12

Subtract 8 from both sides

2x=4

Divide by 2 on the sides

Answer: x=2

Then replace the x's with (2) and multiply

3(2)+8 and (2)+12

Determine the present value P you must invest to have the future value A at simple interest rate r after time t. A $9000.00, r 1
denis-greek [22]

Answer:

P = $6923

Step-by-step explanation:

The simple interest formula is given by

1) I = principal  *interest rate * time period

where I is the interest

The amount due after the time period is given by:

2) T = principal + I

After three months, you have $9.000, so T = 9000. The present value P is the principal. We have that:

9000 = P + I

I = 9000 - P

In our problem, we have that the time period is 3 months and out interest rate is 10%.

Replacing in 1)

9000 - P = P*0,1*3

9000 = 0.3P + P

1.3P = 9000

P = $6923

So the present value P is $6923

A company produces widgets in three factories, A, B and C. Factory A produces 20% of the widgets, factory B produces 45% of the
agasfer [191]

Answer:

1.25% widgets from factory A fail.

Step-by-step explanation:

Probability of widgets that fail = 0.05

Probability of failing widget to belong from factory A = 0.25

Probability of failing widget to belong from factory B = 0.35

Probability of failing widget to belong from factory C = 0.40

Probability of factory A widgets failing = Probability of widgets failing * probability they belonged from factory A

Probability of factory A widgets failing = 0.05 * 0.25 = 0.0125

This probability stated as percentage: 1.25%
