Answer:
<em><1 = <5 ( because it is a corresponding angle and corresponding angles are always </em><em> </em> <em>equal</em><em> </em><em>)</em>

Standard error (SE)

Or

Therefore, SE of the mean = (8)/(2) =4
37.5% of 32 is 12
if you move the decimal point in the percentage 2 places to the left you will get a number you can multiply with
so 0.375 x 32 = 12
The answer to your question would be 0.01
Angle aed has to be 80 since the two triangles share two of the same angles
