Answer:
<W=28.08° or ~28°
Step-by-step explanation:
cosine of<W= adjacent/hypotenuse
=15/17
cosine of<W=[15/17]
[15/17]= 0.8823
but, cosine^-1 [0.8823]
therefore,
W= 28.08° expressed as a whole number
8/17
D. y = -5/7x + 5
5x + 7y = 35
-5x -5x
7y = 35 - 5x
/7 /7 /7
y = 35/7 - 5/7 x
y = 5 - 5/7x
k = 5
y = kx
15 = k(3)
k = 15/3
SA= a+1/2(p)(h)
SA= 18+1/2( 18)(5.2)
SA= 18+46.8
SA=64.8
