How many degress are there in:
`(2)/(5)` straight angle

Answer

To find how many degrees are there in \( \frac{2}{5} \) of a straight angle, we can follow these steps:

### Step 1: Understand the value of a straight angle
A straight angle is defined as an angle that measures 180 degrees.

### Step 2: Set up the equation
We need to find \( \frac{2}{5} \) of a straight angle. Therefore, we can express this mathematically as:
\[ \frac{2}{5} \times 180 \text{ degrees} \]

### Step 3: Multiply the fraction by the straight angle
Now, we will perform the multiplication:
\[ \frac{2}{5} \times 180 = \frac{2 \times 180}{5} \]

### Step 4: Calculate the numerator
Calculate \( 2 \times 180 \):
\[ 2 \times 180 = 360 \]

### Step 5: Divide by the denominator
Now, divide 360 by 5:
\[ \frac{360}{5} = 72 \]

### Conclusion
Thus, \( \frac{2}{5} \) of a straight angle is:
\[ 72 \text{ degrees} \]
