You treat this problem as though it's a regular triangle.
You plug the numbers 24 and 45 into the equation for a triangle which is A=1/2 (L x W)
So what you get is A= 1/2 (24 x 45)
Which can be simplified to A= 12 x 45.
In the end that totals to 540 meters.
Sin = 14/50; 7/25 & tan = 14/48; 7/24, Hope this helps.
Answer:
Step-by-step explanation:
Sum and Difference Formula
cos( U +/- V ) = cosU*cosV -/+ sinU*sinV
cos( U - V ) = cos(70)cos(20) + sin(70)sin(20)
cos( U - V ) = cos (70 - 20)
cos( 50 ) = .642788
