Help me answer this question about congruent triangles. 50 points available.

Anuta_ua [19.1K]

Answer:

Step-by-step explanation:

No these triangles are not congruent.

<u>Left triangle</u>

Shortest side = 6 cm

Longest side = 13 cm

3rd side = unknown but < 13

<u>Right triangle</u>

Shortest side = 6 cm

Longest side = unknown but > 13

3rd side = 13 cm

Although the shortest side of both triangles is 6 cm, the longest side of the left triangle is 13 cm, whereas the longest side of the right triangle is unknown but will be more than 13 cm.

We do not know if any of the angles are congruent. If they were congruent, we would expect to see this marked by the same angle line(s) on each triangle.

Find in simplest radical form, the length of the line segment joining points (1,5) and (3,9)

yaroslaw [1]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}
\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 1 &,& 5~) 
% (c,d)
&&(~ 3 &,& 9~)
\end{array}~~~ 
% distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{(3-1)^2+(9-5)^2}\implies d=\sqrt{2^2+4^2}\implies d=\sqrt{20}
\\\\\\
d=\sqrt{4\cdot 5}\implies d=\sqrt{2^2\cdot 5}\implies d=2\sqrt{5}$

Sally has made a scale drawing of the airplane, in which the wingpsan is 10 inches and the tailspan is 3 inches. What is the act

Nataliya [291]

Wingspan:10 Tailspan:3

10 times 2.4 is 24

So, you would do the same for three and

3 times 2.4 is 7.2

So, your answer is A, 7.2. Hope that helps :) ❤️
