Answer:
1)
2)
Step-by-step explanation:
1)
The two triangles are similar by AA similarity.
That means .
We can add to both sides to get .
We can then subtract from both sides to get .
We know that the because they both lie on a straight line.
We can plug in for to get .
We can divide both sides of the equation by to get .
We then add to both sides to get .
So, and we're done!
2)
Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to , we have that .
We can subtract a and an from both sides to get .
We then divide both sides of the equation by to get .
We do the same thing for . On the other side of the trapezoid, we have that .
We combine like terms on the left side to get .
We subtract a from both sides to get .
We divide both sides of the equation to get .
So, and we're done!

Answer:
<h2>1544 m³</h2>
Step-by-step explanation:
surface area = 2 × base + lateral area
base = (10×20)÷2 = 100
Lateral area = perimeter × height
= (20+14+14)×28
=1 344
Final answer :
surface area = 2 × base + lateral area
= 2 × 100 + 1344
= 200 + 1344
= 1544
