Answer:

x = 20°

Step-by-step explanation:

2x + 5 + x + 25 = 90 \\ 3x + 30 = 90 \\ 3x = 90 - 30 \\ 3x = 60 \\ x =  \frac{60}{3}  \\ x = 20 \\

As it is right angled, thus it will be equal to 90.

= 2x + 5 + x + 25 = 90

= 3x + 30 = 90

= 3x = 60

= x = 60/3

= x = 20

iren [92.7K]

Answer:

Your question cannot be answered with any assurance of being accurate because there is insufficient information. If one were to answer your question, exactly as asked, without interpolating any assumptions, then the answer could be zero because you only stated that he bought the apples but did not state that he left the store or that he left the store with the apples he bought. He could have gone directly to customer service and requested a refund for all the apples, or for all but the three which were just right, or a substitution of some other item for those apples which were bruised or rotten or for all of them, or he could have given the apples to someone else in the store or he could have been in the store with a friend or acquaintance and the friend left the store with the apples and Jared left the store empty handed. Perhaps Jared owns a pet pig and the pig won’t care if the apples are rotten or bruised and Jared bought them at a steep discount, because of their condition, as a treat for his pig. In which case, kudos to Jared for buying his pig a treat.
