Scalene triangle,,,,,,,, a triangle that no side is equivalent to to another
Answer:
Height of the goalpost is 9.25 m.
Step-by-step explanation:
As per the rule of reflection in physics,
Angle of incidence = Angle of reflection
As we can see in the picture attached, both the angles (θ) are equal.
m∠ACB = m∠ECD = 90° - θ
m∠ABC = m∠ADC = 90°
Therefore, both the triangles ΔABC and ΔEDC will be similar.
And by the property of similar triangles, their corresponding sides will be proportional.


ED = 
ED = 9.25 m
Height of the goalpost is 9.25 m.
The answer to the question
Answer:
The width is 18 and the length is 42
Step-by-step explanation:
Well, if you say nine tenths, you know tenths is the first number after the decimal point. So you would put nine in the tenths spot.
