How do I solve for AB? (rounded to the nearest tenth)

Mathematics

Answer:

The answer would be 8.1

Step-by-step explanation:

For the smaller triangle, you use the pythagorean theorem. a squared + b squared = c squared.

To find one of the legs, you do 5 squared - 3 squared = b squared.

25 - 9 = b squared. (BD)

16 = b squared

4 = b

Now for the bigger right triangle. You still use the same tactic.

7 squared + 4 squared = c squared (which is AB)

49 + 16 = c squared

65 = c squared

That means c would equal: square root of 65, which is 8.0622577483 which rounds to 8.1

Write the equation in slope-intercept form. -24x+8y=16
IgorC [24]
-24x+8y=16

Add 24x to both sides:

-24x+8y+24 = 16+24x

8y =16+24x

Divide both sides by 8 :

\frac{8y}{8} = \frac{16+24x}{8}

y = 3x + 2

Axis interception  of 3x+2

x - interception  points of 3x+2 :  ( \frac{-2}{3} , 0 )

y - interception point of  3x+2 : (0,2)

hope this helps!
