Answer:
answer is 57.
Step-by-step explanation:
Given
m<6= x - 8
m<7 = 2x - 7
We know
<6 + <7 = 180° [ being linear pair ]
x - 8 + 2x - 7 = 180°
3x - 15 = 180°
3x = 180° + 15°
3x = 195°
x = 195° / 3
x = 65°
Now
m<6= x - 8 = 65° - 8° = 57°
hope it helps :)
THE SURFACE AREA IS 3220CM^2
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.
