Answer 2

Answer:

14.one acute angle is 12° less than other acute angle

as it is a right angle triangle so one angle is 90°

then other angles are (90-12)°/2=78/2°=39°

and (39+12)°=51°

15. fig 1 .as two sides are equal so x=40°

fig 2. here x=(180-120)°=60°

fig 3 . 90+x=125

=> x=(125-90)°=35°
