Answer 1

Explanation:

1) tan45 = x/10

x = 10(tan45) = 10

cos45 = 10/y

y = 10/(cos45) = 14.14

2) cos26 = 8/x

x = 8/cos26 = 8.9

3) sin60 = y/12

y = 12(sin60) = 10.4

cos60 = x/12

x = 12(cos60) = 6

4) Draw a line from top of triangle straight down and perpendicular to the 15 leg, label it z. This divides the 15 leg into 2 segments: y and (15-y).

cos89 = y/12

y = 12(cos89) = 0.21

sin89 = z/12

z = 12

15 - 0.21 = 14.79

Now you can solve for x:

x² = 14.79² + 12²

x =
`√(362.74)` = 19
