SOH CAH TOA and Pythag. Theorem are all the formulas related to Right Triangles.
With these formulas we can determine angle measurements and side lengths.
Tan 15 degrees = Y/75 (opposite/adjacent)
.26794 = Y/75
Y = 20 (approx.) = opposite side length
Tan 25 degrees = Z/40 (opposite/adjacent)
.466 = Z/40
Z = 19 (rounded to whole number) = opposite side length
To find the last missing side (BC), use the Pythag. Theorem:
20 squared + 19 squared = c squared
400 + 361 = c squared
761 = c squared
c = approx. 28
