<h2>In triangle BDE and triangle BAC</h2><h2>Angle B = Angle B (Common) </h2><h2>Angle BDE = Angle BAC </h2><h2>Therefore, triangle BDE is congruent to triangle BAC (AA similarity) </h2><h2>Hence proved. </h2>
Hope it helps :)
Since we don't know the dimensions of the shape, I can only help you with the procedure.
To find the surface area, you will need to know the height and radius of the cylinder.
Then, the formula is:

If you have those measurements, go ahead and use them. If you don't have them already, you will have to work backwards from the volume to find them.

16
Step-by-step explanation:
by expanding the bracket you'd have -41x+16
Answer:
7 and 12
Step-by-step explanation:
x - y = 5
y = (5+x)
x+ (5+x) = 19
2x +5 = 19
2x = 14
x = 7
19-7 = 12
12 +7 = 19
12-7 = 5
