Answer:
23°, 54°, 103°
Step-by-step explanation:
let the2nd angle = x
1st angle = x + 31
3rd angle = 2(x + 31) - 5 = 2x + 62 - 5 = 2x + 57
Sum the 3 angles and equate to 180
x + 31 + x + 2x + 57 = 180 , that is
4x + 88 = 180 ( subtract 88 from both sides )
4x = 92 ( divide both sides by 4 )
x = 23
Then
1st angle = x + 31 = 23 + 31 = 54°
2nd angle = x = 23°
3rd angle = 2x + 57 = 2(23) + 57 = 46 + 57 = 103°
Answer:
The simplified expression for the given expression will be:
c. 
Step-by-step explanation:
Given expression:

To simplify the expression.
Solution:
In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.
<em>This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.</em>
So, we have:
⇒ 
Combining like terms
⇒ 
<em>The like terms can be evaluated as</em>


Thus, the simplified expression will be:
⇒
