Please explain step by step
Alja [10]

Let's find the value of x

Since the sum of internal angles of a triangle is 180°

therefore,

\hookrightarrow \: (2x - 2) \degree + (x + 5) \degree + 90 \degree = 180 \degree

\hookrightarrow \: 2x - 2 \degree + x + 5\degree  = 180\degree - 90\degree

\hookrightarrow \: 3x + 3\degree = 90\degree

\hookrightarrow \: 3(x + 1) = 3(30)

\hookrightarrow \: x + 1\degree = 30\degree

\hookrightarrow \: x = 29\degree

It is given that, Shyla had a balance of −$255.25 in her account, and Susan had a balance of −$178.75 in her account.

And absolute value of -255.25 =255.25 which is greater than absolute value of -178.75 which is 178.75. It means , Shyla's account balance is more than Susan's account balance . THerefore, Shyla owes the bank more than Susan .
