Question

help me out please!!

Answer 1

Answer:

80° = v + 55° ( Vertically Opposite angle)

v = 80° - 55°

v = 25°

Here, we have used the property of vertically opposite angles which states that the angles which are vertically opposite, measure the same which means they are equal.

Hope it helps you :)

Answer 2

Answer:

$v = 25$

Step-by-step explanation:

Let's say an angle with 80 missing is x

$x + 80 = 180 \\ x = 180 - 80 \\ x = 100$

$x + 55 + v = 180 \\ 100 + 55 + v = 180 \\ 155 + v = 180 \\ v = 180 - 155 \\ v = 25$

I hope I helped you^_^
