Need help with this

The answer is C) 8 cm squared.

That is because 64/8 = 8 cm squared. Hope this helps!!!

Answer:

C. 8 cm2

Step-by-step explanation:

If the big square is 64 cm2, then each side is 8 cm (8cm x 8cm = 64 cm2)

Each of the small squares then has both sides of half the side of the big one, then, each small square has 4cm x 4cm = 16 cm2

Ihen, each small triangle's area (such as ABH) is (b.h)/2, being the base and the height equal to the sides of the small square. Each small triangle is (4cm x 4cm)/2=8cm2

Answer:

Step-by-step explanation:

2) ∠A + ∠B = 146       {Exterior angle theorem}

5y + 3 + 4y + 8 = 146

5y + 4y + 3 + 8 = 146           {combine like terms}

         9y + 11 = 146

               9y = 146 -11

               9y = 135

                 y = 135/9

y = 15

3) m∠A = 5y + 3

              = 5*15 + 3

              = 75 + 3

∠A = 78

4) m∠B = 4y + 8

            = 4*15 + 8

            = 60 + 8

      m∠B = 68

5) m∠ACB + m∠A + m∠B = 180   {Angle sum property of triangle}

 m∠ACB  + 78 + 68 = 180

           m∠ACB + 146 = 180

                       m∠ACB = 180 - 146

                      m∠ACB = 34

Answer:

The figure is rotating clockwise

Step-by-step explanation:

Let us revise the cases of rotation

1. Rotation with positive direction (anti-clockwise)

- If the point (x, y) rotated about the origin by angle 90° anti-clockwise

∴ Its image is (-y, x)

- If the point (x, y) rotated about the origin by angle 180° anti-clockwise

∴ Its image is (-x, -y)

- If the point (x, y) rotated about the origin by angle 270° anti-clockwise

∴ Its image is (y, -x)

2. Rotation with negative direction (clockwise)

- If the point (x, y) rotated about the origin by angle 90° clockwise  (-90°)

∴ Its image is (y, -x)

- If the point (x, y) rotated about the origin by angle 180° clockwise  (-180°)

∴ Its image is (-x, -y)

- If the point (x, y) rotated about the origin by angle 270° clockwise  (-270°)

∴ Its image is (-y, x)

From the given

∵ The figure is rotating around the origin by d degrees

∵ d < 0, which means d is negative

→ According to rule 2 above

∴ The direction of rotation is clockwise

∴ The figure is rotating clockwise
