solve for a, geometry work

Answers

Answer 1

Answer:

a = 45 degrees

Step-by-step explanation:

Since both angles are a, they are equal to each other

Also, we know that the right angle means it measures 90 degrees

So, (180-90)/2 = a

a = 45 degrees

Answer 2

Sum of interior angles in a triangle =180
a+a+90=180
2a+90=180
2a=180-90
2a=90
a=90/2
a=45
