Answer:

40

Step-by-step explanation:

∠BAC and ∠CAD are supplementary angles as they are formed on a line of the triangle.

Supplementary angles add up to 180°

This means ∠BAC + ∠CAD = 180

We are given that ∠CAD = 140

So ∠BAC + 140 = 180

==> subtract 140 from both sides

∠BAC = 40°

d = dimes

q = quarters

d+q = 38 coins

q=38-d

9.5-0.25d+0.10d=6.95

-015d=-2.55

d=-2.55/-0.15 = 17

q=38-17 =21

21*0.25 =5.25

17*0.10 = 1.70

5.25+1.70 = 6.95
