Help on this please.

Mathematics
1 answer:
mote1985 [20]2 years ago

Answer:

x = 11

Step-by-step explanation:

A triangle has three sides, which are its edges. Also, it has three vertices that are the corners of a triangle and where two edges meet.

The circumference is equidistant from the vertices of the triangle:

Equidistant = At equal distances.

The vertices in the picture are: A, B, C

The circumcenter is: P

So, we can apply the rule: PA = PB = PC

PA = 38

PB = 6x - 28

PC = ?

And since the picture labels PA and PB, we set up the equation:

PA = PB = PC

38 = 6x - 28

Add 28 to both sides

38 + 28 = 6x - 28 + 28

66 = 6x

Divide 6 on both sides

66/6 = 6x/6

Simplify

11 = x

Flip the equation

x = 11

Jonathan took 33 pictures on the class trip and 67
Semenov [28]

Answer:

<em>JONATHAN WILL NEED 14 PAGES.</em>

Explanation:

<em>33 + 67 = 100</em>

<em>100 - 12 = 88</em>

<em>88 ÷ 6 = 14.6666667 </em>

<em>14.6666667 ⇒ </em><u><em>14</em></u>

<em>(Round 14.6666667 down to 14 because Johnathan does not have .6666667 of a page.)</em>

. CDEF is a trapezium
guajiro [1.7K]

9514 1404 393

Answer:

  24 cm²

Step-by-step explanation:

To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...

  P = 2(AB +BC)

  BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm

Then CD is ...

  CD = BD -BC = 9 cm -4 cm = 5 cm

The area of the trapezium is given by the formula ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²

The area of trapezium CDEF is 24 cm².
