can you explain more freely about question I did not understand sorry for comments in answet
Answer:
392
Step-by-step explanation:
3 rectangular faces
7 x 16 = 112
7 x 16 = 112
7 x 16 = 112
2 triangular faces
1/2 x 7 x 8 = 28
1/2 x 7 x 8 = 28
Total surface area:
112 + 112 + 112 + 28 + 28 = 392
Answer:
31.6°
Step-by-step explanation:
The triangle given us a right angled Triangle
We solve the above question using the trigonometric function of Tangent
The formula is given as:
tan θ = opp/adj
θ = m∠G = ?
Opposite = EF is 28.2
Adjacent = GF is 45.8
tan θ = 28.2/45.8
θ = arc tan (28.2/45.8)
θ = 31.621459805°
Approximately
m∠G = 31.6°
Question 11:
Isometry is a transformation the preserves the distance and there is no change in the distances. It includes rotation, reflection and translation . Hence the figures are congruent. So the statement is false
Question 12:
A reflection is a transformation where every point of the line is of equal distance from a particular line called the line of reflection
Hence this statement is true
Question 13:
The angle of rotation is the turning of every angle of a figure about a specific fixed point in a specific degree. Hence the statement is true
