There are typically 3 angles, obtuse, acute, and right. obtuse- an angle that measures over 90° acute- an angle that measures less than 90° right- an angle that measures exactly 90°
The 3 interior angles of this equilateral triangle will add up to 180 degrees
Then the other 2 angles will add up to 148 degrees because any triangle has 3 interior angles that add up to 180 degrees
What is the volume of a box what is measures 2 meters × 3 meters × 1 meter
Let the second angle of the triangle be A. Then angle 1 = 2A : and angle 3 = 3A - 12 The internal angles of a triangle total 180° therefore :- 2A + A + (3A - 12) = 180 6A - 12 = 180 : 6A = 192 : A = 32 The angles measure 64° , 32° and 84° .
