Answer:
c) ASA
Step-by-step explanation:
Angles at either end of the shared line segment are marked congruent, so the triangles can be shown to be congruent using the ASA postulate. (The shared segment is congruent to itself.)
Answer:
60 °F
Step-by-step explanation:
The function can be put into vertex form:
T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms
Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.
T(x) = 0.264(x² -18x +81) +81 -0.264·81
T(x) = 0.264(x -9)² +59.616
The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.
Answer:
73
Step-by-step explanation:
The line is 180 degrees and 107- 180= 73
X+y=12
8x+10y=102
8x+8y=96
8x+10y=102 _
-2y= -6
y=3
x+y=12
x=12- 3
x=9
or
8x+10y=102
8x+30=102
8x=102-30
8x=72
x=9
