Step-by-step explanation:
To find a slope with 2/5, you can use y2 - y1/x2 - x1. The 1 and 2's can be different but you cannot mistake the x and y.
1st example:
(1, 5), (6, 7)
Reason: (7-5)/(6-1) = 2/5
2nd example:
(2, 8), (7, 10)
Reason: (10 - 8)/(7 -2) = 2/5
3rd example:
(5, 2), (10, 4)
Reason: (4-2)/(10 -5) = 2/5

Answer:
a = 60°
b = 20°
Step-by-step explanation:
Adjacent angles in a ||gram are supplementary . So,
2a + a = 180°
3a = 180°
a = 60°
Similarly,
2a + 3b = 180°
2(60) + 3b = 180°
120 + 3b = 180°
3b = 60°
b = 20°
