PLZ HELP ASAP LAST SIMMILAR AND CONGRUENT TRIANGLES

Mathematics
1 answer:
JulsSmile [24]3 years ago

Since Y is the right angle of the triangle LNT, LT is the hypotenuse of that triangle. We are going to use the Pythagorean equation to find the measure of LT:
LT= \sqrt{LY^2+TY^2}
LT= \sqrt{5.2^2+3.9^2}
LT=6.5

We can infer from our picture that triangles LNT and YNT are similar. And remember that in similar triangles <span>the corresponding sides are proportional, so we can establish a proportion between sides LT and NT, and between sides  LY and TY:
</span>\frac{LT}{NT} = \frac{LY}{TY}
\frac{6.5}{NT} = \frac{5.2}{3.9}
<span>Solving for NT:
</span>NT= \frac{(6.5)(3.9)}{(5.2)}
NT=4.88
<span>
Now the perimeter of our rectangle LINT will be 2LT + 2NT. 
</span>2(LT)+2(NT)=2(6.5)+2(4.88)=22.76<span>
</span><span>
We can conclude that the perimeter of the rectangle LINT is 22.76 units</span><span>

At a school cafeteria a cold lunch costs $1.80, and a hot lunch costs $3.00. During one school year a teacher spent a total of $
Fudgin [204]

Answer:

H=44

C=87

Step-by-step explanation:

1.8 (C) + 3.00 (H) = 288.6

C= 2H-1

1.8 (2H-1) + 3 (H) = 288.6

3.6 H -1.8 + 3 H = 288.6

6.6 H = 290.4

H= 290.4/6.6 = 44

C=87

How to solve y=7/10x+4/5
valkas [14]

To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.

Ax+By=C

Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

710x+10=y

Question 1
Scrat [10]

Answer:

17.11 meters

Step-by-step explanation:

You are using trigonometry in this problem.

The height of the flagpole represents the side <u><em>opposite</em></u> the given angle.

The base of the triangle is given as 19 meters and represents the side <u><em>adjacent</em></u> to the given angle.

Out of the main trigonomentric functions (sine, cosine, and tangent), only tangent uses both the opposite and adjacent sides.

Tan(angle) = opposite / adjacent

If we plug in what we know into that equation: <em>tan(42 degrees) = h / 19</em>

This means that <em>your answer = 19 * tan(42) = 17.11</em> meters
