Answer:

111 =x

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

29+82 = x

111 =x

Answer:

Step-by-step explanation:

Since all the angles in a triangle add up to 180, you would need to add up the 2 values you have to get the third:

∠3 = 180-82-29

      = 69 degrees

Now you have to subtract this value from 180 because a straight line is 180 degrees:

∠x = 180-69

∠x = 111°

Hope this helps!

Which point is part of the solution of the inequality y 2 12x – 11.
Papessa [141]

Answer:

Point (0,0)

Step-by-step explanation:

Given the inequality y > 12x – 11.

We will check which of the given options will be applied for the inequality

A) (1,0)

Substitute with x = 1 and y = 0

0 > 12*1 - 11

0 > 1   ⇒ Wrong

So, Point (1,0) is not part of the solution of the inequality.

B) (3,2)

Substitute with x = 3 and y = 2

2 > 12*3 - 11

0 > 25  ⇒ Wrong

So, Point (3,2) is not part of the solution of the inequality.

C) (1,1)

Substitute with x = 1 and y = 1

1 > 12*1 - 11

1 > 1   ⇒ Wrong

So, Point (1,1) is not part of the solution of the inequality.

D) (0,0)

Substitute with x = 1 and y = 0

0 > 12*0 - 11

0 > -11  ⇒ True

So, Point (0,0) is part of the solution of the inequality.

Also, see the attached figure which represents the given inequality

The shaded area represents the solution of the inequality, and we can note that point (0,0) is part of the solution of the inequality

How do i solve using the substitution method?<br> x+y=-1 <br> y=-2x
leonid [27]

Answer:

(1, -2)

Step-by-step explanation:

<u>Step 1:  Set the second equation into the first </u>

x + (-2x) = -1

x - 2x = -1

-x / -1 = -1 / -1

x = 1

<u>Step 2:  Solve the second equation </u>

y = -2(1)

y = -2

Answer:  (1, -2)

There are three dials on a combination lock. Each dial can be set to one of the numbers 1, 2, 3, 4, 5 The three digit number 553
Anika [276]

The number of different three-digit numbers that can be set for the combination lock is 125

<h3>How to determine the number of different locks?</h3>

The digits are given as

Digit = 1, 2, 3, 4, 5

Each digit can be repeated on the number lock.

So, the individual digit of the lock can be any of the 5 digits.

So, we have:

Locks = 5 * 5 * 5

Evaluate

Locks = 125

Hence, the number of different three-digit numbers that can be set for the combination lock is 125
