Answer:

  • \bf x=7^o

Step-by-step explanation:

When two parallel lines are crossed by a transversal, co-interior angles They are called co-interior angles.  The sum of the two angles on the same side of the transversal is always 180°.

\bf 120^o+7x+11=180^o

\bf 7x+120+11=180

\bf 7x+131-131=180-131

\bf 7x=49

\bf \cfrac{7x}{7}=\cfrac{49}{7}

\bf x=7^o

Answer:

x = 7

Step-by-step explanation:

corresponding interior angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line

one is an obtuse and one is an acute angle in which sum up to 180°

(120°) + (7x + 11) = 180°

120° + 7x + 11 = 180°

131° + 7x = 180°

131° - 131° + 7x = 180° - 131°

7x = 49°

7x/7 = 49°/7

x = 7°

plug x in to check:

7(7) + 11 = 49 + 11 = 60

nevsk [136]

Explanation:

Here's one way to go at it.

Draw segments AB and CO. Define angles as follows. (The triangles with sides that are radii are all isosceles, so their base angles are congruent.)

  x = angle OAB = angle OBA

  y = angle OAC = angle OCA

  z = angle OBC = angle OCB

Consider the angles at each of the points A, B, C.

At A, we have ...

  angle CAB = x + y

At B, we have ...

  angle CBA = x + z

At C, we have ...

  angle ACB = y + z

The sum of the angles of triangle ABC is 180°, as is the sum of angles in triangle ABO. This gives ...

  x + x + ∠AOB = (x+y) +(x+z) +(y+z)

  ∠AOB = 2(y+z) = 2∠ACB

This shows ∠AOB = 2×∠C, as required.

Answer:

It doesn't make sense

Step-by-step explanation:

Given

Statement: .... at a speed of 35 miles .....

Required

Does it make sense?

In motion, speed is measured in km/h, m/s, miles per hour (depending on context) while distance is measured in km, m or miles.

However, the given statement mention the unit of speed to be miles which is incorrect.

Hence, we can conclude that the statement does not make sense.

A correct statement would be: <em>I drove at a speed of 35 miles per hour .......</em>

Domain F(x) = All real numbers and the Range F(x)  [ -2 ,  + ∞ ]

<h3>What is the domain and range of a function?</h3>

A domain is the set of values for which the given function is defined.

Range is the set of all values which the given function can output.

The curve points are

P₁ ( -1,5 , 0 )   Q ( 0. -2 ) and P₂ ( 1,5 , 0 )

We can see that P₁  and P₂ are symmetric around the y-axis, and point Q looks like a vertex so we can conclude the curve as

ax² + bx + c = y

The curve is a parabola

when x = 0      

y = -2    

then   c  = - 2

The equations we get,

a (-1.5)²  +  b (-1.5) + c = 0      

2.25a  - 1.5b - 2 = 0

a (1.5)²   +  b ( 1.5)  + c = 0    

2.25a + 1.5b -2 = 0

Adding these two equations

4.5a - 4 = 0

a =  4/4.5

The vertex is Q ( 0 , -2 )

x = - b/2a      

0 = - b/ 9      

b  =  0

Therefore the equation of the function :

ax² + c = 0

(4/4.5) x² - 2 = 0

Therefore, Domain F(x) = All real numbers and the Range F(x)  [ -2 ,  + ∞ ]
