= 20+20

=40

is your answer

Hope it helps..

40

Step-by-step explanation:

2+2+2+2+2+2+2+2+2+2+20 = 40

Step-by-step explanation:

From the triangles given in the figure,

Given:

AC ≅ AD

m∠ABC = m∠ABD = 90°

To prove:

ΔABC ≅ ΔABD

Solution:

          Statements                           Reasons

1). AC ≅ AD                        1). Given

2). AB ≅ AB                       2). Reflexive property

3). ΔABC ≅ ΔABD             3). By HL theorem for congruence of the triangles
