  • EK+KR=ER
  • EK+EK=ER
  • 2(EK)=ER
  • 2(x+5)=4x+2
  • 2x+10=4x+2
  • -2x=-8
  • x=4

KR:-

  • x+5
  • 4+5
  • 9

Answer:

KR = 9

Step-by-step explanation:

If K is the midpoint of ER, then EK = KR and ER = 2(EK).

Given:

  • ER = 4x + 2
  • EK = x + 5

         ER = 2(EK)

⇒ 4x + 2 = 2(x + 5)

⇒ 4x + 2 = 2x + 10

⇒ 2x + 2 = 10

⇒ 2x = 8

⇒ x = 4

As EK = KR  and EK = x + 5  and x = 4:

⇒ KR = 4 + 5    

⇒ KR = 9

Mrac [35]

Answer:

Step-by-step explanation:

5. x/7 = 9/x

x^2 = 63

x= 3\sqrt{7}

6. x/84 = 16/x

x^2 = 1344

x=8\sqrt{21}

7. x/12 = 12/16

16x=144

x=9

How many triangles can be made with a 70 degree angle a 30 degree angle and an 80 degree angle​
uranmaximum [27]

Answer:

There are infinite number of triangles that could be achieved with those angles.

To picture this, we only have to imagine a triangle that is either smaller or bigger than the one at hand.

Tracing a series of paralell lines (which guarantee that the angles are being kept),  we can draw triangles for infinite values of x,y and z.
