Answer: <1 = 26°
Step-by-step explanation:
given that:
• <ABD = 66°
• <2 = 14° + <1 (since ''more than' means we add)
• Find <1
Since it is obvious that <ABD is a sum of <1 and <2:
⇒ <ABD = <1 + <2
now we know that <2 is 14° more than <1 and that <ABD = 66°
⇒ 66° = <1 + (14° + <1)
⇒ 66° = <1 + 14° + <1
⇒ <1 = (66° - 14°) ÷ 2
⇒ <1 = 26° ...Answer...

Answer:
After 7 minutes both the tanks will have the same amount of water.
Step-by-step explanation:
The water is filling in a tank at the rate of 75 L/mins from an initial 550 L of water and water is removing from another tank at the same rate from the initial 1600 L of water.
Let us assume that the same amount of water will be there in both the tanks after t minutes.
Therefore, 550 + 75t = 1600 - 75t
⇒ 150t = 1050
⇒ t = 7
Therefore, after 7 minutes both the tanks will have the same amount of water. (Answer)
