Answer 1

x = 45

Explanation:

We see that the triangle is both a right-angled triangle and an isoceles triange. This means that the three angles are:

a 90

b = c

c = b

We also know that the maximun amount of degrees in a Euclidean triangle is 180 degrees, so

2x = 180 - 90

180 - 90 = 90

90 = 2x

90 / 2 = 45

So, x = 45
