<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
4y=5x+4
Divid by 4 to make slop intercept form
Y=5/4y +1
Slop =5/4
Answer:
EF= 5.5
Step-by-step explanation:
7 + 4 = 11
11 divided by 2 = 5.5
3x + 1 - 8x +12 =
so 8x - 3x =5x
1 + 12= 13
so answer is 5x+13
