1. **Problem Statement:** Given a spherical triangle with angles $A=90^\circ$, $B=100^\circ$, and $C=92^\circ$, find the side $b$ opposite angle $B$. 2. **Relevant Formula:** In sp

1. The problem states that in a spherical triangle, the angles are given as $A=90^\circ$, $B=100^\circ$, and $C=92^\circ$. 2. We need to determine which rule is used to solve a sph

1. **Problem statement:** Two pilots start from point P on a spherical Earth (radius 6378.1 km). Pilot 1 flies at initial bearing N 34° E to point Q, and Pilot 2 flies at initial b

1. **State the problem:** We have a spherical triangle with angles $A$, $B=90^\circ$, and $C=95^\circ$, and side $a=100^\circ$. We want to find angle $A$ using one of the given tri
