Step-by-step explanation:

use Pythagoras theorem,

{a}^{2}  +  {b}^{2}  =  {c}^{2}

{6}^{2}  +  {8}^{2}  =  {c}^{2} \\ 36 + 64 =  {c}^{2}  \\ c = \sqrt{100 }   \\ c = 10

Answer:

The length of missing side of triangle is <u>10 m</u>.

Step-by-step explanation:

<h3><u>Solution</u> :</h3>

Here, we have given that the two sides of triangle are 6 m and 8 m.

Finding the third side of triangle by pythagorean theorem formula :

{\longrightarrow{\pmb{\sf{{(c)}^{2} = {(a)}^{2} + {(b)}^{2}}}}}

  • \pink\star a = 6 m
  • \pink\star b = 8 m
  • \pink\star c = ?

Substituting all the given values in the formula to find the third side of triangle :

\begin{gathered} \qquad{\longrightarrow{\sf{{(c)}^{2} = {(a)}^{2} + {(b)}^{2}}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = {(6)}^{2} + {(8)}^{2}}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = (6 \times 6)+ (8 \times 8)}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = (36)+ (64)}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = 36 + 64}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} =100}}}\\\\\qquad{\longrightarrow{\sf{c = \sqrt{100}}}}\\\\\qquad{\longrightarrow{\sf{c = 10 \: m}}}\\\\\qquad\star{\underline{\boxed{\sf{\red{c = 10 \: m}}}}}\end{gathered}

Hence, the length of missing side of triangle is 10 m.

A 5-foot ladder leans against a wall. The base of the ladder is on the ground, 2.5 feet from the wall. What is the measure of th
tatuchka [14]

Answer:

c) 60°

Step-by-step explanation:

We solve this question using trigonometric function of Cosine.

cos θ = Adjacent/Hypotenuse

θ = ???

Adjacent = Base of the ladder is on the ground = 2.5 feet

Hypotenuse = Length of the ladder = 5 feet

cos θ = 2.5/5

θ = arc cos (2.5/5)

θ = 60°

Therefore, the measure of the angle created by the ladder and the ground is 60°

Answer:

  (6, -3)

Step-by-step explanation:

The midpoint of a segment is the average of the end point coordinates.

  F = (C + L)/2

  F = ((0, 0) + (12, -6))/2 = (0+12, 0-6)/2 = (6, -3)

The fire station coordinates are (6, -3).
