Answer: 83.\overline{3}\text{ feet}

Step-by-step explanation:

Since, In the given diagram,

The sides of the triangles ABC and EDC are,

BC = 62 feet, DC = 93 feet and DE = 125 feet(given)

And, angles B and D are right angles,

⇒ \angle ABC\cong \angle EDC

\text{Also, } \angle ACB\cong \angle ECD    ( Vertically opposite angles )

By AA similarity postulate,

\triangle ABC\sim \triangle EDC

The sides of similar triangles are in same proportion ,

⇒  \frac{AB}{ED}=\frac{BC}{DC}

⇒  AB \times DC = BC \times ED

⇒  AB = \frac{BC.ED}{DC}

By substituting the values,

We get,

⇒  AB = \frac{62\times 125}{93}

⇒  AB = \frac{7750}{93}=83.\overline{3}\text{ feet}

A line passes through the points (2,-4) and (6,10). What is the equation of the line?
deff fn [24]

Answer:

y = \frac{7}{2} x - 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (6, 10)

m = \frac{10+4}{6-2} = \frac{14}{4} = \frac{7}{2} , thus

y = \frac{7}{2} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, - 4) , then

- 4 = 7 + c ⇒ c = - 4 - 7 = - 11

y = \frac{7}{2} x - 11 ← equation of line
