The Calculation of an Unknown Angle

Let's dive into a fascinating mathematical problem together! We're going to calculate the value of an unknown angle, which is represented by the expression: (3-1+4-1+5-1)°.

Step-by-Step Solution

To solve this problem, we'll follow the order of operations (PEMDAS):

1. Evaluate the expressions inside the parentheses

Inside the parentheses, we have a mix of additions and subtractions. Let's evaluate them step by step:

(3 - 1) = 2 (2 + 4) = 6 (6 - 1) = 5 (5 + 5) = 10 (10 - 1) = 9

So, the expression (3-1+4-1+5-1) equals 9.

The Unknown Angle

Now that we've calculated the expression, we can conclude that the unknown angle is:

(3-1+4-1+5-1)° = 9°

There you have it! The unknown angle measures 9 degrees.
