Answer:
125 degrees
Step-by-step explanation:
Add up the angles you have, then subtract them from 180 degrees.
30+25=55
180-55=125
125°
(The sum of angles in a triangle is 180 degrees.)
So you then add up all the other numbers you have in the triangle as:
30°+25°= 55°
And you then it from 180° as:
180°-55°= 125°
