Question

A² + b² = c² b = 35 C = 37 a = 11 a = 14 a = 18 a = 12

Answer 1

a=12

Step-by-step explanation

`a^2+b^2=c^2`

if

b=35

c=37

a=?

Step 1

replace,

`\begin{gathered} a^2+b^2=c^2 \\ a^2+35^2=37^2 \\ a^2+1225=1369 \\ \end{gathered}`

Step 2

subtract 1225 in both sides,

`\begin{gathered} a^2+1225=1369 \\ a^2+1225-1225=1369-1225 \\ a^2=144 \end{gathered}`

Step 3

make square root in both sides

`\begin{gathered} a^2=144 \\ \sqrt[]{a^2}=\sqrt[]{144} \\ a=12 \end{gathered}`

I hope this helps you
