Answer:
A = 45°
B = 110°
C = 25°
Step-by-step explanation:
The interior angles given are:
A = x°,
B = (x + 65)°
C = 25°
We know that sum of the interior angles of a triangle = 180°, therefore,
x° + 25° + (x + 65)° = 180°
Solve for x
x + 25 + x + 65 = 180
Add like terms
2x + 90 = 180
2x = 180 - 90 (subtraction property of equality)
2x = 90
x = 90/2 (division property of equality)
x = 45
✔️Measures of the interior angles are:
A = x = 45°
B = (x + 65)° = (45 + 65)° = 110°
C = 25°
