The answer to the above question can be explained as under -
We know that, the sum of angles of triangle is 180°.
So, vertex angle plus base angles are equal are equal to 180°.
Let the vertex angle be represented by "v" and base angles be represented by "b".
Thus, v + b + b = 180°
So, v + 2b = 180°
Next, the question says, the vertex angle is 20° less than the sum of base angles.
Thus, 2b - 20° = v
<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>

Answer:
D.x=4
Step-by-step explanation:
5(x-6)+3=-7
distribute 5(x-6) which would be 5x-30+3=-7
5x-27=-7
add 27 to -7
5x=20
then divide
x=4
