Answer: Top right corner (northeast corner)
Angle IAE = Angle DAH
These two angles are vertical angles as shown in the diagram below. Vertical angles are always congruent.
1 foot = 12 inches
Height of Jacob = 5 feet 6 inches = 5 *12 + 6 = 66 inches
Jacob's <span>shadow = 3 feet = 36 inches
</span>giraffe's shadow = <span>5 feet 9 inches = 5 * 12 + 9 = 69 inches
</span><span>by
the ratio and proportion
∴ </span>Height of Jacob/Jacob's shadow = Height of giraffe/giraffe's shadow
∴ 66/36 = Height of giraffe/69
∴ Height of giraffe = 69 * 66/36 = 126.5 inches = 10 feet 6.5 inches
Answer:
1) They were multiplied by one power of ten because 2.5x 1^10 is 25, and so that it is easier to divide.
19.625/ 2.5 * 10/10 = 196.25/25
Hope this helps plz hit the crown ;D
