Question

Help me please thank y’all

Answer 1

45 degrees

Explanation:

We know that angle 4 equals angle 2 because corresponding angles are congruent.

So x+30 = 2x+15,

We subtract 15 from both sides,

x + 30 - 15 = 2x + 15 - 15

x + 15 = 2x

Now we subtract x from both sides,

x - x + 15 = 2x - x

15 = x

x = 15 degrees

So we plug this in angle 4,

15 + 30 = 45 degrees
