Two sides and the included angle of a triangle are found by measurement to be 40 ft, 33 ft, and 60° respectively. If there is a possible error of 0.65 foot in measuring each side and 0.5° in measuring the angle, what is approximately the greatest possible error in the computed value of the third side?

IN TRIANGLE ABC, ANGLE C = 70 DEGREES.. IF AB = 10, AND ANGLE A = 60 DEGREES, THEN COMPUTE THE MEASURE OF BC, TO 2 DECIMAL PLACES.​​​​​​​

At an altitude of 12,000 ft, a pilot sees two towns through angles of depres- sion of 37° and 48° as 37 12,000 shown. To the nearest 10 ft, how far apart are the towns?
