Answer:
The angles are Complementary Angles.
x = 55°
Explanation:
the angles are Complementary Angles, because when added, together they form a 90° angle.
•to find the value of x, we form the equation :
⇒90° = x° + (x - 20)°
⇒90 = x + x - 20
⇒90 = 2x - 20
•shifting the 2x to the left side and the 90 to the right side
⇒2x = 90 + 20
⇒2x = 110
•shifting the 2 to the right side
⇒x = 110/2
⇒x = 55° Answer...
