The third side is = 4
This is a perfect square. Also, using the Pythagorean theorem you can find the third side
3squared + xsquared = 5 squared
9 + xsquared = 25
xsquared = 16
sqrt of 16 = 4
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.
Sum of internal angles on same side of transversal is 180
(8x-14) +(2x+54) =180
10x +40 =180
10x =140
x=14
option D x=14 is correct
Answer: the answer is c. 420
Step-by-step explanation:
this is because
V= L*W*H
SO
V= 12*14*5
But since there is a triangle as the base you divide by 2 or multiply by 1/2
1/2( 12*14*5)= to 420
so the answer is 420
