<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
2 3/8 / 1 1/4
= 19/8 / 5/4
=19/8 * 4/5
= 19/10
answer is B 19/10
Answer:
Infinitely many solutions
Step-by-step explanation:
Answer:
y-5=3x-15
Step-by-step explanation:
Slope=(5+1)/(-6+8)
=6/2
=3
Equation of line passing throgh point (-6,5):
y-5=3(x-5)
y-5=3x-15
Eliminate y by writing the bottom equation into the top one:
-1/2x - 4 - 3x = 3
-3.5x = 7
x = -2
y= -1/2 * -2 - 4 = -3
