Answer: Square
Step-by-step explanation:
A cross section cut parallel to a base will be the same shape as the base itself, and the base of a cube is a square. :)
Cot A=1/tan A=12/5
cos A= 12/13
sin A=5/13
Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
<u>Answer:</u>
20h + 20
<u>Step-by-step explanation:</u>
5(2h + 4) + 10h
1️⃣ Expand by distributing terms.
<em>10h + 20 + 10h</em>
2️⃣ Collect like terms.
<em>(10h + 10h) + 20</em>
3️⃣ Simplify.
<em>20h + 20</em>
Answer: <em>20h + 20</em>
