I'm assuming that the full statement is ΔABC is congruent to ΔDEF.
Given:
m∠A = 70
m∠B = 47
m∠C = 63
Since both triangles are congruent, the corresponding angles in ΔDEF also has the same measure as those in ΔABC.
m∠D = 70
m∠E = 47
m∠F = 63
The measure of angle F is 63.
F(x) = 3x ; where x is the number of books purchased.
x f(x)
0 0
1 3
2 6
3 9
4 12
5 15
I saw this problem and the instruction was to graph the function and show the domain and range.
The domain is all the x-values while the range is all the y-values.
8,8,8 would be the answer
