What is the length of if ?<br><br> 8 in.<br> 8.75 in.<br> 10.25 in.<br> 14 in.
Ket [755]

Answer:

A=8.75 in.

Step-by-step explanation:

Since ∆ HBA & ∆HKJ are similar,  

HB/HA = HK/HJ  

3/5.25 = 8/HJ  

3HJ/5.25 = 8  

3HJ = 42  

HJ = 14 in.

AJ = 14 - 5.25  

AJ = 8.75 in.

Therefore

A=8.75 in.

I hope this helped you.
