952 ft squared

Step-by-step explanation:

Surface area, is just the area of all the faces added together.

So, the sides we need to find are measuring:

Triangle side: 10 x 8

Triangle Face; 10 x 8

Square Face: 10 x 10

Square Face: 10 x 10

Rectangular Face: 14 x 10

Rectangular Face: 14 x 10

Bottom Rectangular face: 14 x 10

Side of the Triangular prism: 9 x 14

Side of the Triangular prism: 9 x 14

Because the triangle face has two of them, we only have to do one as opposed to dividing the same face twice.

So, we have a side of 80.

From here, it is just multiplication.

80 + 100 + 100 + 140 + 140 + 140 + 126 + 126 = 952 ft

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
