Answer:
3. d = 15 ; c° = 90°
4. s = 12 ; t° = 71°
Explanation:
Figures are similar.
Therefore:
3. In the rectangles one is 3 times bigger than the other. each side is multiplied by 3.
We can find d : 5*3 = 15
Also, the angles are equal 90° angles.
4. The other shape is similar but it is up side down.
one is 6 times bigger than the other. We can fins by multibliying the same side of the small shape by 6 : 2*6 = 12
The angle t° is the same angle oposite to the 90° angle but in the right position. Remember the Shape is up side down,
Therefore: t° = 71°
