Question

in triangle abc ab is8cm and angle a 50°and angle is 70° find the perpendicular distance from c toab find the area of triangle​

Answer 1

Answer:

Since Area of Triangle ABC (which is not a right triangle…so we need to call in our trigonometric friends to the rescue) = (1/2) times sides BC times AB times (sin 150 degrees).

This translates to 1/2 x 6 x 8 x (sin 150) =24 x (0.5) =12 sq. cm : Answer.

Note: sin 150 degrees is 0,5
