make an equation - example, two sides are 2x+60-4x+5=180
equal them to 180 because every triangle is equal to 180
when you find x, multiple two times x plus 60,
s x plus 5
thats the only thing i know about it

24) all angles are equal and the angles add up to 180, so 180/3, x=60.
25) we already know that the middle angle is 90. So same as above all angles add up to 180. 2x+90+x=180. 3x=90, x=30.
26) again adds up to 180. x + x + 25= 180. 2x=155, x=77.5.
