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.

Answer:
85° and 95°
Step-by-step explanation:
Given that , x and x + 10 are a pair of angles .
- If they will be pair of angles on the same line , then their sum will be 180° .
=> x + x + 10° = 180°
=> 2x = 180° -10°
=> 2x = 170°
=> x = 170°/2
=> x = 85° .
<h3><u>Hence </u><u>the </u><u>two </u><u>angles</u><u> </u><u>are </u><u>8</u><u>5</u><u>°</u><u> </u><u>and </u><u>9</u><u>5</u><u>°</u><u> </u><u>.</u></h3>
