Answer:
The answer is 5 .
Step-by-step explanation:
You have to substitute the values of a, b and c into the expression :

Let a = 5,
Let b = 5,
Let c = 10,



Answer:
85° and 95°
Step-by-step explanation:
Given that , x and x + 10 are a pair of angles .
- If they will be pair of angles on the same line , then their sum will be 180° .
=> x + x + 10° = 180°
=> 2x = 180° -10°
=> 2x = 170°
=> x = 170°/2
=> x = 85° .
<h3><u>Hence </u><u>the </u><u>two </u><u>angles</u><u> </u><u>are </u><u>8</u><u>5</u><u>°</u><u> </u><u>and </u><u>9</u><u>5</u><u>°</u><u> </u><u>.</u></h3>
