Answer:
x = 70°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an external angle of the triangle, thus
x + 50 = 120 ( subtract 50 from both sides )
x = 70
The total area of the figure will be 245 sq. in.
<h3>Total area of a cylinder</h3>
The figure is a cylinder and the total area of a cylinder is given by the formula below:
Total Area of a cylinder = 2πrh+2πr^2
Where r is the radius, h is the height of the cylinder, and π is constant with a value of 22/7.
In this case, looking at the image, the radius is 3" while the height is 10". Substituting these values into the formula above, we have:
Total Area = 22/7((2x3x10) + (2x3^2)) = 22/7(60+18)
= 245 sq. in.
Thus, the total area of the solid figure is 245 sq. in.
