ll that apply. Triangle A B C. Angle B is a right angle.
2 answers:
Answer:
Options (1), (2) and (4).
Step-by-step explanation:
Given question is incomplete; Find the complete question in the attachment.
Triangle ABC is a right triangle.
ΔABC has been dilated by a scale factor of 2 forming ΔA'B'C'.
These are the observations,
1). A and A' will be co-linear.
2). Since the given triangle has been dilated about a point B therefore, after dilation vertex B and B' will at be same location.
3). Length of B'C' = 2BC
4). AB and BC are the segments which will lie on the sides BA' and BC'.
5). Pre-image ABC will be inside the image A'B'C'.
Therefore, Options (1), (2) and (4) will be the answer.

Answer:
The temperature decreased by 9 °F in <u>6 days.</u>
Step-by-step explanation:
Let the number of days it takes for the temperature to decrease by 9 °F be .
Given:
Average daily temperature decreases by °F.
Decrease of temperature in 1 day = = 1.5 °F.
∴ Decrease in temperature in x days is .
Now, as per question, decrease in temperature in 'x' days is 9 °F.
Therefore,
Therefore, the temperature decreased by 9 °F in 6 days.
