Answer:
step 2
Step-by-step explanation:
Gary didn't multiply the 2.5 and 4 correctly. The product isn't 8, it is 10.
So using trigo ;
cos D =base/hypo
cosD =23.5/33.8 = 0.695
so and D = 45.97°
thus angle F = 180-(90+45.97) =44.03°
so your answers are 45.97° and 44.03° or you can say 45° and 45°....approx !!
8 gallons equals 64 pints
