Which equation is related to sqrt(x+10)-1 =x

x + 10 = x² + 2x + 1

Step-by-step explanation:

- 1 = x

x + 1 =

Squaring both sides gives;

(x + 1)² = ()²

x + 10 = x² + 2x + 1

option B

Step-by-step explanation:

the given equation is,

.................................(1)

adding  both side by 1 in equation (1)

squaring both side              

x + 10 = ( x + 1 )²                

we know,

( a + b )²  = a² + b² + 2 a b

x + 10 = x² + 2 x + 1

hence, the correct answer is option B.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
