Question

The angles of the triangles ABC and DEF are given as follows :
$A={90}^0,B={30}^0,D={90}^{0}andE={30}^0.$
If the side BC is twice the side EF, then

• A. sin B $=$ 2 sin E
• B. sin E $=$ 2 sin B
• C. sin B $=$ sin E
• D. sin A $=$ sin F

Answer 1

Answer: (C)

sin B $=$ sin E

$\angle B=\angle E$
Hence, $sinB=sinE$
