Answer:
Step-by-step explanation:
Set this up as a proportion, with width on the top of the ratio and length on the bottom and fill in according to the info you've been given:
x is the unknown width we are looking for. Cross multiply to get
8x = 60 so
x = 7.5
200π m²
Lateral area of a cone = πrl
r = 8 m
l = 25 m
Plug in the values
Lateral area = π × 8 × 25
Lateral area = π × 200 = 200π m²
X=12°
y=60°
75=6x+3
x=12°
y=180-(45+75)
