Answer:
x=35 degrees
Explanation:
The 125 degree angle and the angle right next to it (inside the triangle) add up to 180.
180-125 = 55 degrees.
All 3 inside (interior) angles of a triangle = 180.
So we know that top angle = 90 degrees. (That little square means that it's a 90 degree right triangle.)
And that bottom right angle is 55 degrees.
So we just need to find x.
180 = x+ 55 + 90
180 = x + 145
180-145 = x
35 = x
So x = 35 degrees.
Check that everything adds up: 35+90+55 = 180
I'm sorry you are grounded :(
