Please Help The question is in the picture

So, tangents are equal to each other when they come to a point. So, all you have to do is set 3x+10 and 7x-6 equal to each other. 3x+10=7x-6 subtract 3x from both sides 10=4x-6 and now add 6 to both sides to get 16=4x, divide by 4 on each side and x=4. If you could give me brainliest that would be super helpful!
