Answer:

  • 11) 3
  • 13) 27°

Step-by-step explanation:

11. ..................................................

The triangle is isosceles

Equal sides have length of

  • 5x - 11 = 3x - 3
  • 5x - 2x = 11 - 3
  • 3x = 9
  • x = 3

13. ..................................................

The triangle is isosceles

x is one of the angles of a right triangle

The other angle of this triangle is same as corresponding angle = 63°

  • x = 90° - 63°
  • x = 27°

Answer:

<h2>11.   x = 4</h2><h2>13.  x = 27°</h2><h2 />

Step-by-step explanation:

<u />

<u>11.  isosceles triangle with two equal side lengths</u>

     5x - 11 = 3x - 3

     5x - 3x = 11 - 3

     2x = 8

      x = 8 / 2

      x = 4

<u>13. isosceles triangle mirrored right triangle</u>

    with angles 63°, 90° and x , find x

    90 + 63 + x

    90 - 63 = x

     x = 27°

Factorise completely
ycow [4]

Answer:

a) 9a(x - 3b) - 4(x - 3b) = (9a - 4)(x - 3b)

b) 5a(2b - 3) - 4(2b - 3) = (5a - 4)(2b - 3)

c) x(2h - k) + 3y(k - 2h)

= x(2h - k) - 3y(2h - k)

= (x - 3y)(2h - k)

What are the coordinates
anzhelika [568]

Answer:

(1.5,1)

Step-by-step explanation:

I don't know how to explain. I used GeoGebra and I put the coordinate down and then made lines. Line AC and line BD. Then I put a point on where it intersects and it comes out to (1.5,1). You can also use distance formula, but that is more work.
