Answer:w=3
Step-by-step explanation:
Recognize that the triangle is isosceles, so the two side lengths are equal.
b = 2√2
Recognize it is a right triangle, so you can use the Pythagorean theorem to compute the length of "a".
a^2 = (2√2)^2 +(2√2)^2
a^2 = 8 +8 = 16
a = √16
a = 4
Answer: y= 3 or -2/3
Step-by-step explanation:
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.
