Answer:
13.41 cm
Step-by-step explanation:
The radius, height, and HALF of vertical angle makes a triangle.
Where
Radius will be the base of the triangle
Height will be the "height" of the triangle
Top angle will be HALF of vertical angle (40/2 = 20)
From the 20 degree angle, the side "opposite" would be the radius, which is 30. The side "adjacent" would be the height, let it be h.
<em>Which trig ratio relates opposite and adjacent? Yes, that is TAN. Thus we can write:</em>
Tan(20) = opposite/adjacent
Tan(20) = 30/h
h = 30/Tan(20)
h = 13.41
So
The height of the cone would be around 13.41 cm
Answer:
y = -0.3x + 103
Step-by-step explanation:
✔️Find the slope (b):
Slope = ∆y/∆x
Using, (25, 95.5) and (35, 92.5),
Slope (m) = (92.5 - 95.5)/(35 - 25) = -3/10 = -0.3
✔️Find the y-intercept (b):
Substitute (x, y) = (25, 95.5) and m = -0.3 into y = mx + b
95.5 = -0.3(25) + b
95.5 = -7.5 + b
95.5 + 7.5 = b
103 = b
b = 103
✔️To write the equation, substitute m = -0.3 and b = 103 into y = mx + b
Thus:
y = -0.3x + 103
No because the hundred place doesn't move.
