Answer:
80% off
Step-by-step explanation:
(0.15 - 0.75)/0.75 = -0.8 = -80%
Answer:
Exact form: 9/10 , Decimal form: 0.9
39.5 I think that's the answer I hope its right if wrong than I'm truly srry
Answer:

Step-by-step explanation:
Given two non zero vectors,
.
Let the angle between the two vectors = 
Given that:

Let us have a look at the formula for magnitude of addition of two vectors:

Where
is the angle between the two vectors.
formula for magnitude of subtraction of two vectors:

As per the given condition:

Squaring both sides:

So, the angle between the two vectors is: 
Answer:
The correct option is;
C) AA Similarity Postulate
Step-by-step explanation:
The given parameters are;
BE║CD Given
∠A is congruent to ∠A Reflective property
∠ACD is congruent to ∠ABE Corresponding angles formed by parallel lines and a transversal
∠ADC is congruent to ∠AEB Corresponding angles formed by parallel lines and a transversal
ΔABE ~ ΔACD AA Similarity Postulate
When two angles of one triangle are equal to the corresponding two angles of another triangle, given that the third angle of both triangles are also equivalent based on sum of angles of a triangle postulate, the two triangles are said to be similar based on Angle-Angle (AA) Similarity Postulate.
