Answer:
61
Step-by-step explanation:
straight line = 180 degree
to find the measure of angle QPR,
subtract 119 from 180
=> 180-119
=> 61
angle QPR = 61 degree
Chess board? , the board if there is like a line with points that has points on the same line.
Answer = 0
n can have possible values from (-12) to 12
-12 <= n < 12
(-12) + (-11)+(-10)......+10+11+12=0
If you factor the equation you can see what the solutions are. Two factor a quadratic of the form ax^2+bx+c, find two values which satisfy two conditions...
jk=ac=-15 and j+k=b=-2 so j and k must be -5 and 3 so the factors are:
(x-5)(x+3)
So the other solution is x=5
