Sagot :
sum∠ of the interior angle m∠easures of a triangle m∠ust be 180°
(all triangles are 180°)
We are given that m∠3 = 48°
So, m∠1+m∠4= 180° - 48° = 132°
answer = 132°
from∠ the figure, we can see that m∠2+m∠3 = 180° = answer
when two angles add up to 180°, then they are called
SUPPLEm∠ENTARY angles
Since m∠3 = 48°, it m∠ust be that m∠2 is 180° - 48° = 132°
answer is 132°
Therefore, m∠2 = m∠1+m∠4
This result is an example of the Exterior Angle Property of Triangles.
For any triangle, the measure of an exterior angle is
equal to the sum of it's interior opposite angles
m∠2 = 132°
m∠2 = m∠1+m∠4
