Vladimir79 [104]

Answer:

<h2>9.656cm</h2>

Step-by-step explanation:

Applying  SOH CAH TOA

The opposite to the angle 44° is the height

let the height be x meters

The distance from the both to the lighthouse is 110 meters which is the adjacent

Applying Tan ∅= opp/adj

The equation used to find the height is Tan ∅= opp/adj

Tan (44)=\frac{x}{110} \\\0.9656= \frac{x}{110} \\\\0.9656*10= x\\9.656=x\\x= 9.65cm

The height is 9.65cm

Anyone know the answer? Also could you put down what equation I’m supposed to use?
goldenfox [79]

Answer:

The bottom two are your answers.

Step-by-step explanation:

What you do is use the slope formula which is y_2-y_1/x_2-x_1.

So for PQ it will be 12(which is y_2)-6(which is y_1)/4(which is x_2)-5(which is x_1) which equals -6.

12-6/4-5=-6.

Answer:

28 units

Step-by-step explanation:

Since, given triangles have same perimeters.

\therefore \: 5x + 5x + 3x + 2 = 6x + 3 + 2x + 1 + 4x \\  \\ 13x + 2 = 12x + 4 \\  \\ 13x - 12x = 4 - 2 \\  \\ x =  2 \\  \\ \implies 12x + 2 = 12( 2) + 4 = 24 + 4 = 28 \: units \\  \\ \&\: 13x + 2 =13(2) + 2 = 26 + 2 = 28  \: units\\  \\

So perimeter of each triangle is 28 units
