Can a triangle have side lengths 3,13, and 7

1 answer:

6 0

No. This is because the two smaller lengths must be greater than the largest length (7+3=10) this is less than 13 meaning the triangle won’t work

Triangle ABC and DEF are right triangles, as shown. Triangle ABC is similar to triangle DEF. which ratios are equal to sin C?

Dafna11 [192]

Answer:

First option and Fourth option.

Step-by-step explanation:

To solve this exercise you need to use the following Trigonometric Identity:

$sin\alpha=\frac{opposite}{hypotenuse}$

In this case you know that:

$\alpha =C$

Since triangle ABC is similar to triangle DEF:

$\angle C=\angle F$

Let's begin with the triangle ABC.

You can identify that:

$opposite=AB\\hypotenuse=AC$

Then, substituing values, you get:

$sinC=\frac{AB}{AC}$

In triangle DEF, you know that:

$opposite=DE\\hypotenuse=DF$

So, substituing values, you get:

$sinF=sinC=\frac{DE}{DF}$

What is the solution to this problem (1,3)(5,k) m=2

Mazyrski [523]

Answer:

The solution of given problem is k = 11

Step-by-step explanation:

<u>slope of given two points formula:-</u>

slope m = $\frac{y_{2}- y_{1} }{x_{2}-x_{1} }$ .....(1)

Given points are (1,3) and (5,k)

given slope m = 2

now substituting m =2 and the given points are (1,3) and (5,k)

$2 = \frac{k-3}{5-1}$

on simplification we get solution

$k-3 = 8$

$k = 8 +3$

$k = 11$
