Explanation:
Ist one
180 - (90+25+35)=30 (Its a triangle so overall it equals 180 so you just subtract that from all the angles.)
2nd one
180-(114+36)=30. (Divide up triangle and find one side._
30+32=62 (add the angle you found and 32 to find overall)
180-(36+62) = 82 ( Don't include 114 because it isn't part of the overall triangle.
3rd one
180-(90+76)=14( Divide up triangle first and work from there)
180-(76+43)= 61 ( Use full triangle to find out what the upper part should equal to)
x= 61-(15+14)= 32(Use what the upper side should equal to, to help you find what x is.)
2nd page
1- 180- 48= 132 (Angles on a straight line add up to 180)
2- 180-(90+38)=52 (Angles on a straight line add up to 180)
3- 360-(75+78+89)=118 (Angles that look like that add up to 360)
4- 180- (110+24)= 46(Angles in a triangle equal 180)
5-180-(90+23)= 67(Angles in a triangle equal 180)
6-180-(65+65)=50( Since the lengths outside the triangle are the same, then the angle will also be the same and also angles in a triangle add up to 180)
