Option -A

30 Degrees

mark me brainilist okay

Answer 2

Answer:

45 degrees

Step-by-step explanation:

Because a triangle has 180 degrees in total

because right angles means that it has one 90 degree and Iscoceles means that the other two are equal therefore the other two are 45 degrees each.

180 = 90 + 2x

=> 45 degrees

2x because they are equal
