Your answer should have been 3850 in^2
1^2/5^2 = 1/25
1/25 = 154/x
1x= 154 (25)
1x/1= 3850/1
x= 3850
-1/2 + 2 = 1.5
because if u add 2 to a minus half it goes 0 and then 1.5 (positive half)
For the 51-deg angle, y is the opposite leg, and 12 is the hypotenuse.
The trig ratio that relates the opposite leg and the hypotenuse is the sine.
sin A = opp/hyp
sin 51 deg = y/12
y = 12 * sin 51 deg
y = 9.3
