Step-by-step explanation:
There are 3 angles in a triangle and the sum of the 3 angles is 180°.
Since one of the angles is 45°, the sum of the other 2 angles is 135°.
These other 2 angles are equal in magnitude, hence one of them is 135°/2 = 67.5°.
Answer:
67.5
Step-by-step explanation:
you have 180
one angle is 45
so its 180-45 = 135/2 which is 67.5
so 67.5 + 67.5 + 45= 180
