Equation practice with angle

Mathematics
1 answer:
cestrela7 [59]2 years ago
7 0

Answer & Step-by-step explanation:

AOC is a straight angle. Straight angles have a measurement of 180°. ∠AOB and ∠BOC make up ∠AOC. So this measn that when you add ∠AOB to ∠BOC, then they should have a sum of 180°.

<em>m∠AOB + m∠BOC = 180°</em>

<em>m∠AOB = 3x + 142</em>

<em>m∠BOC = 6x + 29</em>

Now, set up the equation.

<em>3x + 142 + 6x + 29 = 180</em>

<em>9x + 171 = 180</em>

<em>9x = 9</em>

<em>x = 1</em>

Now that we have the value of x, then we can find the measurement of ∠BOC.

m∠BOC = 6(1) + 29

m∠BOC = 35

So, the measurement of ∠BOC is 35°

If someone could work out the first half of the problem and explain that would be great!
andrew-mc [135]

Answer:

x = -5

y = -5

Step-by-step explanation:

If you multiply the top equation by negative 2, you can add it to the bottom equation and cancel out the x:

-2(-x + 5y = -20) --> 2x - 10y = 40

Add this to the bottom equation top to bottom:

2x - 10y = 40

-2x + 4y = -10

You get:

-6y = 30

Then solve for y:

y = -5

Plug this back in for either equation and solve for x:

-x + 5(-5) = -20

-x -25 = -20

-x = 5

x = -5

Your answers are:

x = -5

y = -5

Suppose that P(n) is a propositional function. Determine for which improper subset of the domain of n the statement P(n) must be
Alinara [238K]

Answer:

a) P(n) is true for all 'n' in the set ; { 0,2,4,6,8 ….. }

b) P(n) is true for all 'n' in the set ; { 0,1,2,3,4,5 ............ }

Step-by-step explanation:

a) As P(0) is true

we will assume that

  • P(2) is true
  • P(4) is true
  • P(6) is true

this simply means  that ;  P(n) is true for all 'n' in the set

{ 0,2,4,6,8 ….. }

b) since P(0) and P(1) are true

we will assume that

  • P( 0+2 ) = P(2)  is true

also P(1) and P(2) are true

we will assume that

  • P(1+2) = P(3)  is true

Also from the previous answers it can be seen that P(2) + P(3) is true

we will assume

  • P(2+2) = P(4)  is true

This simply means that P(n) is true for all 'n' in the set

{ 0,1,2,3,4,5 ............ }
