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>

Part A:

Function A:

Slope = (7-3)/(5-3) = 4/2 = 2

Equation:

y - 3 = 2(x - 3)

y - 3 = 2x - 6

y = 2x - 3

Funcion B:

(0, 3 ) and (-5, 0)

Slope = (3 - 0)/(0 + 5) = 3/5

y-intercept (0,3) so b = 3

Equation:

y = 3/5 x + 3

Function C:

y = 3x + 1

Part B:

Rate of change is the change in y over the change in x (rise/run). It's also the slope

Function A:     rate of change = 2

Function B:     rate of change = 3/5 (smallest)

Function C:     rate of change = 3   (largest)

Order linear functions based on rate of change from least to greatest.

Function B:             y = 3/5 x + 3

Function A:             y = 2x - 3

Function C:             y = 3x + 1

What equation do you get when you solve z-m=z+bx for x
Sonbull [250]
Z-m=z+bx

z-m-z=z+bx-z

-m=bx

bx=-m

bx/b=-m/b; b=0

x=-m/b; b=0

Find the coordinates for the midpoint of the segment with endpoints given. (12, 4) and (-8, 8) (2, 6) (10, 6) (2, 2)
cluponka [151]
The given coordinates are:
p1: (12,4) and p2: (-8,8)

Th x coordinate of the midpoint is calculated as follows:
Xmidpoint = (x1+x2) / 2 = (12+-8) / 2 = 4/2 = 2

The y coordinate of the midpoint is calculated as follows:
Ymidpoint = (y1+y2) / 2 = (4+8) / 2 = 12/2 = 6

Based on the above calculations, the midpoint of the segment with the given coordinates is (2,6)
