pls solve 11 problem as soon as possible urgent

➡Given here
two point are (x,7) and (1,15)
distance between these point = 10.
So,
using Formula
distance between two point
10 = √[(x-1)²+(7-15)²]
=>Squaring both sides
100 = (x-1)²+(-8)²
=>(x-1)² = 100-64
=>(x-1)² = 36
=>(x-1) = ±√36
=>x = ±√36 +1
✔Now take here +ve sign and -ve sign
➡So, first take +ve sign
=>x = 36+1
=>x = 37
➡Now ,take -ve sign
=>x = -36+1
=>x = -35
Thus:-
value of x will be
37, or -35
✨Thats answer✨
Step-by-step explanation:
Given points
(x, 7) (1,15)
Distance between two points
=√(x2-x1) +(y2-y1)
10= √(1-x) ^+(15-7) ^
10 = √(1+x) ^-2x+64)
10=√(x^-2-2x+65)
squaring to each other
100 = x^ -2x +65
x^ -2x - 65 -100 = 0
x^ -2x -35 = 0
x^ -7x -5x -35 = 0
x(x-7) + 5(x-7) = 0
(x+5) +(x-7) = 0
x+5=0 , x-7=0
therefore, x= -5 , y= 7
hope it helps
