How was ABCDEFGH transformed to A'B'C'D'E'F'G'H'?
Yanka [14]
So ur going from a smaller shape to a larger shape....means the scale factor is more then 1. The scale factor is the number that u multiply the original shape by to get the other shape.

so lets look at DE...it is 2.....and D'E' is 6

so 2 * x = 6...with ur scale factor being x
2x = 6
x = 6/2
x = 3.....so the scale factor is 3....because multiplying the original shape by 3, gives u the other shape

Please help me, its just question 11-14 !!
emmainna [20.7K]

Answer:

11- 64 degrees

12- 66 degrees

13- 89 degrees

14- 99 degrees

Step-by-step explanation:

11. 100 + 130 + 66 = 296

360 - 296 = <u>64</u>

12. 103 + 133 + 58 = 294

360 - 294 = <u>66</u>

13. 154 + 88 + 29 = 271

360 - 271 = <u>89</u>

14. 101 + 92 + 68 = 261

360 - 261 = <u>99</u>

hope this helps :)
