Yo sup??
by Pythagoras theorem we can say that
DE²=3²+2²
=9+4
DE=√13
=3.60 units
angle D=tan-1(2/3)
=33.7
angle E=tan-1(3/2)
=56.3
Hope this helps
Answer:
DEsq = 3sq + 2sq
= 9 + 4
DE = √13 = 3.6
sinD = 2/3.6
= 0.555
D = sin inverse 0.555
= 33.71°
cosE = 2/3.6
= .555
E = cos inverse 0.555
= 56.28°
hope it helps :D
