one thing to be noteworthy is that this triangle has two angles, a 60° one and a 90° one, meaning the last angle will be a 30° one, thus we can use the 30-60-90 rule.
Check the picture below.
Answer:
see below
Step-by-step explanation:
27) y = kx
18 = k(20)
18 = 20k
k = 0.9
28) y = kx
-9 = k(3)
-9 = 3k
k = -3
y = -3x
29a) y = kx
5 = k(1/3)
5 = 1/3k
k = 15
y = 15x
29b) y = 15x
y = 15(-2)
y = -30
-3:3,-3:35,-3, 4,15;0,305
