Answer:
a) ∆RLG ~ ∆NCP; SF: 3/2 (smaller to larger)
b) no; different angles
Step-by-step explanation:
a) The triangles will be similar if their angles are congruent. The scale factor will be the ratio of any side to its corresponding side.
The third angle in ∆RLG is 180° -79° -67° = 34°. So, the two angles 34° and 67° in ∆RLG match the corresponding angles in ∆NCP. The triangles are similar by the AA postulate.
Working clockwise around each figure, the sequence of angles from lower left is 34°, 79°, 67°. So, we can write the similarity statement by naming the vertices in the same order: ∆RLG ~ ∆NCP.
The scale factor relating the second triangle to the first is ...
NC/RL = 45/30 = 3/2

b) In order for the angles of one triangle to be congruent to the angles of the other triangle, at least one member of a list of two of the angles must match for the two triangles. Neither of the numbers 57°, 85° match either of the numbers 38°, 54°, so we know the two triangles have different angle measures. They cannot be similar.
Its 40% because its just the fact ratio you know
Answer: b=2(square root of 2) and a=4
Step-by-step explanation:
Since this is a 45-45-90 triangle we know that side b is equal to 
.
In a 45-45-90 triangle, the hypotenuse is equal to 
this means in order to find missing side length a, we have to multiply 
this will give us 4
so the missing side lengths are, and 
Answer:
Length = 6 + 23 = 29 feet
Step-by-step explanation:
Width = x
Length = x + 23
2x + 2(x+23) = 70
2x + 2x + 46 = 70
4x = 70-46
x = 24/4
x = 6
Now, a ferris wheel is a circular
motion machine correct me if I'm wrong, so we have to start on ground
level, meaning that we have to start from any y=0.
The first graph does not start from 0, I do not really believe the poor
child had to vlimb the ferris wheel to take a seat.
