Step-by-step explanation:

By Pythagoras Theorem:

{y}^{2}  =  {(9 + 3)}^{2}  -  {(6)}^{2} \\  \\   {y}^{2}  =  {(12)}^{2}  -  {(6)}^{2} \\  \\   {y}^{2}  = 144 -  36 \\  \\  {y}^{2}  = 108 \\  \\  {y}  =  \sqrt{108}  \\  \\  {y}  =  \sqrt{36 \times 3}  \\  \\ {y}  =  \sqrt{ {6}^{2}  \times 3}  \\  \\ {y}  =  6\sqrt{3}\:units

Help with #9 pleaseeee
Molodets [167]

Answer:

9' - 1.29"

Step-by-step explanation:

Total rise = 5' - 2"

Total run = 7' - 6"

1' = 12" = 1 feet = 12 inches

5' = 5 * 12 = 60"

3' = 7 * 12 = 84"

Total rise = 60" + 72" = 62"

Total run = 84" + 6" = 90"

Length of stringer = hypotenus

Hypotenus = √(total rise² + total run²)

Hypotenus = √(62² + 90²)

Hypotenus = 109.28860"

Convwrting back to feet and inches

= 9' - 1.29"
