Answer:
B 110.5
Step-by-step explanation:
Given that,
The slant height of a cone, l = 17 inches
The diameter of a cone, d = 13 inches
Radius, r = (D/2) = 6.5 inches
We need to find the lateral surface area of a cone. The formula for the lateral surface area of a cone is given by :
Put all the values,
So, the lateral surface area of the cone is equal to .
180
at45% is white and its 81 so i can tell 50% is 90 so I multiplied that by two and got 180

yah yeet yeet yah
37+61+x=180
98+x=180
x=180-98
x=82°
the third angle is 82°
