Answer:

BC = 4.5 (1 dp)

Step-by-step explanation:

<u>Pythagoras’ Theorem</u>

a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

  • a = AC = 1.5
  • b = AB = 4.2
  • c = BC

Substituting these into the formula and solving for BC:

\implies 1.5^2+4.2^2=BC^2

\implies 2.25+17.64=BC^2

\implies BC^2=19.89

\implies BC=\pm\sqrt{19.89}

As distance is positive,

⇒ BC = 4.5 (1 dp)

Sladkaya [172]

Answer:

Below!

Step-by-step explanation:

Solve for  y.

Rewrite in slope-intercept form.

Use the slope-intercept form to find the slope and y-intercept.

Any line can be graphed using two points. Select two  x  values, and plug them into the equation to find the corresponding  y  values.

Graph the line using the slope and the y-intercept, or the points.

What is -4=r/20-5? <br> Is it r=20
castortr0y [4]

Answer:

r = 20

Step-by-step explanation:

-4 = r/20 - 5

-4 + 5 = r/20 - 5 + 5

1 = r/20

1 * 20 = r/20 * 20

r = 20

Please help me with this
Len [333]

Answer:

60 degrees

Step-by-step explanation:

To first solve this problem, we need to figure out the size of an interior angle for a regular hexagon.

This can be done with the formula :

angle = \frac{(n-2)*180}{n} , with n being the number of sides

A hexagon has 6 sides so here is how we would solve for the interior angle:

\frac{(6-2)*180}{6}=120 , with n= 6 sides

Now that we know that each interior angle in the hexagon is 120 degrees, we can now turn our attention to the rhombus.

The opposite angles of the rhombus are congruent, so the two larger obtuse angles are congruent, and so are the two smaller acute angles.

It is also important to note that a rhombus is a quadrilateral, so all of its interior angles add up to 360 degrees.

Looking at the rhombus, we already know one of the angles because it is shared by the interior angle of the hexagon, so the two larger angles in the rhombus are both 120 degrees.

But what about the smaller angles? All we need to do is subtract the two larger angles form 360 and divide by 2 to find the angle.

\frac{360-2(120)}{2} = 60 , so the smaller angle in the rhombus is 60 degrees.

Now that we know both the interior angle and smaller angle of the rhombus, we can find x.

Together, angle x and the angle adjacent to it makes up an interior angle of the hexagon, so x plus that angle is going to equal to 120 degrees.

All we need to do is solve for x:

x+60=120

x=120-60

x = 60 degrees
