Answer:
x = 38
Step-by-step explanation:
3x-16+x+6+x = 180
5x -10 = 180
5x = 180 + 10
x = 190 / 5
x = 38
Answer:
82.5°
Step-by-step explanation:
This is the case of a isosceles triangle , as you may know in a isosceles triangle , there are two sides of equal length as well as two equal angles.
You know that the sum of angles in a triangle is 180°, therefore it comes to this equation :
15° + 2x = 180°
2x = 165°
x = 82.5°
therefore 82.5° is the correct answer.

Answer: lateral surface area = 119.4cm^2
r = 2 cm.
h = 9.5 cm.
Steps:
Lateral surface area of a cylinder = 2πrh
r = radius h = height π = pi
2π(2)(9.5)
2π(19)
38π = 119.38052
