a = x,7

b = 1,15

$ab = \sqrt{(x1 + x2) {}^{2} + (y2 - y1) {}^{2} } \\ 10 = \sqrt{ {x}^{2} + 2x + 1 + 64 } \\ 100 = x + 1 + 64 \\ x = 35$

hope it helps

Answer 2

Answer:

$\huge\fcolorbox{black}{pink}{Answer-}$

$ab = \sqrt{ {(x1 - x2)}^{2} {(y1 - y2)}^{2} } \\ 10 = \sqrt{(x - 1) {}^{2} + 64} \\ 100 = x - 1 - 64 \\ x = 35$

Hope that helps
