Question

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

Answer 1

Answer:

Using Pythagorean theory : a²+9²=15²

=> a²=225-81=144

=> a = √144 = 12

Step-by-step explanation:

Answer 2

Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

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

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

• Value of a

$\underline{ \underline{ \text{Solution}}} :$

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

⤏ $\tt{ {p}^{2} = {h}^{2} - {b}^{2} }$

⤏ $\tt{ {a}^{2} = {15}^{2} - {9}^{2} }$

⤏ $\tt{ {a}^{2} = 225 - 81}$

⤏ $\tt{ {a}^{2} = 144}$

⤏ $\tt{a = \sqrt{144}}$

⤏ $\tt{a = \sqrt{ {(12)}^{2} } }$

⤏ $\tt{a = 12}$

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

Hope I helped ! ツ

Have a wonderful day / night ! ♡
