Solution of Right Triangles

Solution of Right Triangles

By Venus Daydayan

​In the three right triangles, we notice very minimal or basic information about each of them. How do we find the remaining sides and angles ?​

​opposite side

​opposite side

Adjacent side

​Let the adjacent side be b, and the hypotenuse be c. Let us solve for b and c and the missing angle.

​Use scientific

calculator to get sin44.

​Use scientific

calculator to get tan 44.

​The complement of 46 degrees is 44 degrees.

​

The triangle has the solutions 44^0, 46^0, 5 cm, 7.20 cm and 5.18 cm.​
