4. -10b and 6b, 15 and -5
5. -20 and 30, 4c and -2c
Correct Answer:
First Option
Let the first integer be n.
Since the integers are consecutive, the integer next to n will be n+1
and so the third integer will be n+2
Therefore, the three integers are:
n , n +1, n+2
Their sum is 75. So we can write the equation as:
n + (n+1) + (n+2) = 75
This equation can be used to find n. After finding n, we can find the next two integers by finding (n+1) and (n+2)

Step-by-step explanation:
Answer:
<h2><u><em>
55°</em></u></h2>
Step-by-step explanation:
the sum of the interior angles of a triangles is 180°
so
180 = 75 + 50 + x
x = 180 - 75 - 50
x = 55°
-----------------------
check
55 + 75 + 50 = 180°
the answer is good
