Answer:
∠
° 
and 
Step-by-step explanation:
Given:
≅
From the given Data, we can conclude the following:
1. Since two sides of the triangle ABC are congruent, therefore its an isosceles triangle.
2. 
°. This shows that the line BE is perpendicular to AC. By property of isosceles triangle, the line which passes from the vertex of the largest angle of triangle and cuts the opposite side(base) perpendicularly is the perpendicular bisector of the side and angle bisector of the angle.
∴ 
[ Definition of Angle bisector]
∴
[ Definition of perpendicular bisector]
Answer:
It is right
Step-by-step explanation:
Because the hypotenuse must be greater than all the legs, we have that 
is the hypotenuse. So, we want to determine if 
.
This means the triangle is indeed right!

Answer:
tanΘ = - 
Step-by-step explanation:
Using the trigonometric identity
tan²Θ + 1 = sec²Θ, thus
tan²Θ + 1 = (
)² = 
( subtract 1 from both sides )
tan²Θ = 
( take the square root of both sides )
tanΘ = ± 
Since 270 < Θ < 360 , that is the fourth quadrant where tan Θ < 0, thus
tanΘ = -
