Answer:

b = 77

Step-by-step explanation:

a² + b² = c²

36² + b² = 85²

1296 + b² = 7225

b² = 7225 - 1296

b² = 5929

\sqrt{b^2} =\sqrt{5929}

b = 77

Plz someone help me
makvit [3.9K]
Let me break this down a little bit:

Joe has a savings account with $422 in it.

He also has a credit card, meaning that whatever he spends on his credit card, he'll have to pay back later.

So far, he has purchased $524 worth of merchandise.

If you subtract $422 from $524 it will equal =$122 he owes.

Therefore, Joes overall balance is reflected as a POSITIVE number.

The $122 dollars is represented as what he owes which would be a NEGATIVE number.

The ultimate answer to this question is POSITIVE.

Hope this helps! :)

Work out the value of x
zalisa [80]

Answer:

x = 67.5°

Step-by-step explanation:

A circle's angles add up to 360°

So,

x+3x+90 = 360

4x+90 = 360

4x = 360-90

4x = 270

Dividing both sides by 4

x = 67.5°
