Question

help with this !!!!!!!!!!!!!!!!!!!!

Answer 1

Using Pythagorean theory : a²+9²=15²

=> a²=225-81=144

=> a = √144 = 12

Explanation:

Answer 2

Explanation:

`\underline{ \underline{ \text{Given}}} :`

• Hypotenuse ( h ) = 15
• Perpendicular ( p ) = a
• Base ( b ) = 9

`\underline{ \underline{ \text{To \: find}}} :`

• Value of a

`\underline{ \underline{ \text{Solution}}} :`

`\underline{ \text{USE \: PYTHAGOREAN \: THEOREM}} :`

⤏
`\tt{ {p}^(2) = {h}^(2) - {b}^(2) }`

⤏
`\tt{ {a}^(2) = {15}^(2) - {9}^(2) }`

⤏
`\tt{ {a}^(2) = 225 - 81}`

⤏
`\tt{ {a}^(2) = 144}`

⤏
`\tt{a = √(144)}`

⤏
`\tt{a = \sqrt{ {(12)}^(2) } }`

⤏
`\tt{a = 12}`

`\red{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \tt{12 \: \text{units}}}}}}}`

Hope I helped ! ツ

Have a wonderful day / night ! ♡
