Answer:
A. 45 and 135
Step-by-step explanation:
Recall: two angles on a straight line forms a linear pair. The pair sum up to 180°.
Thus:
✔️c° + 3c° = 180°
4c = 180
Divide both sides by 4
4c/4 = 180/4
c = 45°
✔️3c = 3(45) (substitution)
= 135°
Answer:
30 cm.
Step-by-step explanation:
We can solve this problem by making a proportion:
1 cm/65 km = x cm/1,950 km
By cross-multiplying, we can solve for x:
65x = 1,950
x = 30
Choose an equation that would be used to solve 0 = -x2 + 10x – 8
Answer: (x-5)^2=17
