8n + 22 = 70
-22 -22
8n = 48
n = 48/8
n = 6
n*3 = 3n = 6*3 = 18
3n = 18
Answer:

Step-by-step explanation:
Based on the definition of complementary angles, the two angles are: 49.4° and 40.6°.
<h3>What are Complementary Angles?</h3>
Angles that are complementary angles have a sum of 90 degrees.
Let the angle be represented as x
Complement of the angle = (90 - x)
Therefore, we would have:
x = (90 - x) + 8.8
x = 90 - x + 8.8
x = 98.8 - x
x + x = 98.8
2x = 98.8
x = 98.8/2
x = 49.4°
The second angle would be: 90 - 49.4 = 40.6°
The angles are 49.4° and 40.6°.

Answer:
∠2 = ∠3 is a pair of Vertical Angles.
Step-by-step explanation:
Whenever two lines intersect with each other, the angle formed between them is called Vertically Opposite Angle.
Here, line l intersects the traversal so,
the angle formed between them ∠1 and ∠4 are vertically opposite.
So, ∠1 = ∠4
Also, as ∠1 + ∠3 = ∠2 + ∠4 = 180° (LINEAR PAIRS)
So, ∠3 = ∠2 are also vertical angles.
