Question

А support wire 12 yards long is attached to the top of a utility pole 10

Answer 1

Answer:

6.6 yd

Step-by-step explanation:

$a^{2}$+$b^{2}$=$c^{2}$

$10^{2}$+$b^{2}$=$12^{2}$        Substitute a= 10 and c=12

100+$b^{2}$=144      Evaluate the Powers

$b^{2}$=44               Subtract 100 on both sides.

b=$\sqrt{44}$             Square root both sides b>0 so you dont need ⊥

b=6.6              Use a calculator to evaluate.
