Answer: 3 acute angles
and 2 acute angles, 1 obtuse angle
and 2 acute angles, 1 right angle
Step-by-step explanation:
the key is just to imagine it
also you have to know that right angle is 90° acute is less than 90° and obtuse is more than 90°
20% of 120 is 25. You have to cross multiply and divide.
-2x + xy = 30.....when y = 8
-2x + 8x = 30
6x = 30
x = 30/6
x = 5 <==
