Answer:
The answer is 30° and 90°
Step-by-step explanation:
3x°+12x-30°=180°. (Linear pair)
15x-30°=180°
15x=180-30
x=150°/15
x=10°
Therefore, the angles are 3x=3×10°=30° and 12x-30=12×10-30=120-30=90°
30° and 90°

Angles are and .
Step-by-step explanation:
Given:
Angle 1
Angle 2
To Find:
Value of
Calculation:
- When two lines intersect as shown in figure, there are angles formed. Two adjacent angles are called linear pair angles.
- Adjacent angles are formed when two angles have a common vertex and a common arm but do not overlap.
- The linear pair of angles are always supplementary as they form on a straight line.
Supplementary angles sum up to .
So,
Since value of is .
Therefore Angle 1
Angle 2
