Volume of cylinder is 402.1238....=402.12ft
Volume of rectangle is 1344ft
Add both together= 1746.12ft

Surface area of rectangle:
Length=14ft
width= 8ft
height =12ft

14x12=168x2=336
8x12=96x2=192
14x8=112x2=224
336+192+224=752

Surface Area of cylinder:

Radius= 4ft
height=8ft
2π r h+2π r^2
2π4(12)+2<span>π4^2
2</span>π48+2<span>π16
301.59+100.53=402.42ft

Add both surface area together=1154.12ft</span>

The missing angle of the given triangle  is 59°.

What is vertically opposite angles?

  Angles that are vertically opposed to one another are always equal to one another. A vertical angle and the angle to which it is next are also supplementary angles; that is, they sum up to 180 degrees. As an illustration, if two lines connect to form an angle, say X=45°, then the angle's opposite angle is also 45°.

Here consider angle with 31° and 49° triangle is 1. We know that sum of all angles in triangle is add upto 180°. Then,

⇒ 49°+31°+x = 180°

⇒ 80° + x= 180°

⇒x= 180°-80°=100°

Then unknown angle in triangle 1 ia 100°.

Now according to the vertically opposite angle theorem , opposite angles are equal to each other. Then ,

In triangle 2 angle is 100° and 21°. Then missing angle is,

⇒ 100°+21°+missing angle =180°

⇒Missing angle = 180°-100°-21°

⇒Missing angle = 59°

Therefore the answer is 59°.
