Answer:
155°
Step-by-step explanation:
The sum of the 4 interior angles of a quadrilateral = 360°
Subtract the sum of the 3 given angles from 360 for fourth angle
fourth angle = 360° - (60 + 45 + 100)° = 360° - 205° = 155°
The sign for -18 9/17+(-18 917) is -.
The answer is -3 because u plug in (8,0) to the equation 8+y=5 , next u minus 5 from 8 and get -3. hope that helps!!
Answer: Use distributive property
Step-by-step explanation:
Answer:

Step-by-step explanation:
Let the numerator of the fraction=x
Since the denominator of a fraction is two more than the numerator.
Denominator=x+2
The fraction is therefore:

If both numerator and denominator are decreased by six, the fraction becomes:

The simplified result is 
Therefore:

Substituting x=40 into the initial fraction

Therefore, the original fraction is
