52'

Step-by-step explanation:

there's a 90'

so you do :

90 - 26

which is : 64'

and since the triangle is iscoscelese, then that means there will be another side that is 64'

so then you do :

180' - 64' - 64' = x

52 = x

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2
