I need help ASAP pls show ur work and ty

Step-by-step explanation:

x + 0.7 = 1 - 0.2x

Add 0.2x to both sides

x + 0.2x + 0.7 = 1 - 0.2x + 0.2x

1.2x + 0.7 = 1

Subtract 0.7 from both sides:

1.2x + 0.7 - 0.7 = 1 - 0.7

1.2x = 0.3

Divide both sides by 1.2:

1.2x/1.2 = 0.3/1.2

x = 0.25

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
