Brainly to whomever somehow solves for x. I WILL REPORT SCAMS AND UNHELPFUL "WHAT?" ANSWERS.
cestrela7 [59]

Answer:

x=\frac{33}{7}

Step-by-step explanation:

Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.

Therefore, we have:

\frac{11}{11+x}=\frac{14}{20},\\14(11+x)=20\cdot 11,\\11+x=\frac{20\cdot 11}{14},\\x=\frac{110}{7}-11=\boxed{\frac{33}{7}}

Suppose a triangle has sides a b and c and the angle opposite the side of length a is obtuse.What must be true?
VikaD [51]
When a triangle is obtuse, the length of c^2 is bigger than the combined lengths of a^2 and b^2.

a^2+b^2<c^2

"A" is the best answer.

I hope this helps!

ZanzabumX [31]
<h3>I'll teach you how to distribute −2x(−10x+1)</h3>

----------------------------------------------------

−2x(−10x+1)

Apply the distributive law:

Ex. of distributive law:

a(b+c)= ab+ac

-2x(-10x)+(-2x)*1

Apply minus/plus rule:

2*10xx-2*1*x

Simplify 2*10xx-2*1*x:

2*10xx= 20x^2

2*1*x= 2x

20x^2-2x

Your Answer Is 20x^2-2x

plz mark me as brainliest if this helped :)
