Answer:
Step-by-step explanation:
It is important to remember that, by definition, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
In this case we can idenfity that the angle 
is an exterior angle of the triangle QRT. Then:
Where:
Substituting values and solving for "x", we get:
Then:
The sum of the interior angles of a triangle is 180°, therefore:
Solving for 
, we get:
Answer:
315
Step-by-step explanation:
Each of the 15 teams plays each of the other 14, for a total of 210 games. However, that count includes both A playing B and B playing A. Hence, if the teams meet 3 times, the total number of games will be 3/2 this amount:
(15)(14)(3/2) = 315 . . . league games
Answer:
c
Step-by-step explanation:
c because 11 and 16 have no GCF other than 1
That is the answer Y=x^-8x12, xER
Answer:
Slope m=4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
We have A(0,-2)->x1=0, y1=-2
B(2,6)->x2=2, y2=6
