we have the following information from a right triangle
hypotenuse, h =

and, short leg, a =

we need o calculate the larger acute angle
1. Let's draw this triangle and identify the angle in question
Angle Θ is the largest acute angle because it's opposite to the larger leg
We can calculate this angle using the following

then
![\theta=\arccos (\frac{\sqrt[]{6}}{\sqrt[]{15}})=50.77](https://img.qammunity.org/2023/formulas/mathematics/college/mvp6amzgu568h8pj4unia0g9m5wfh7mgrn.png)
Rounding to the nearest tenth of a degree:
larger acute angle of the triangle, Θ = 50.8°
