Bunny's climb form a Right Angled Triangle as shown in the figure. The hypotenuse and the perpendicular side of the Right Angled Triangle are known , we are to find the angle made by the bunny.
Sine can be used to related these three terms as sine of angle is equal to perpendicular divided by hypotenuse.
[tex]sin(x)= \frac{42}{100}=0.42 \\ \\
x= sin^{-1}(0.42) \\ \\
x=24.83 [/tex]
Rounding of to nearest tenth, the jump made by bunny was at angle of 24.8 degrees
