Answer:
D = 90°
E = 147°
F = 33°
Step-by-step explanation:
E:
E is 147°, because it is vertical to the angle 147°
F:
F is 33°, because 147* is its supplementary angle, or angles that add up to 180°
D:
D is worth 90°, because its supplement is worth 90°
-Chetan K
A=h*b/2
180 =(b-2)*b/2
360 = b^2-2b
b^2 -2b -360 =0
D = 4+1440 = 1444
b_1,2 = (2+/-sqrt1444)/2 = -18 and 20
base length equal 20 in
height equal 18 in
