angle A = 130°

x=65°

I hope it's helps you

(2x - 30°) + 50° = 180° (linear pair angles)

2x + 20° = 180°

2x = 180° - 20°

2x = 160°

x = 160°/2 = 80°

Now, A = 2x - 30° = 160°-30° = 130°

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
