The Pythagoras Theorem:

the base squared and height squared added is equal to the hypotenuse squared.

(x+6)² + (x+3)²= (x+9)²

x²+36+12x+x²+9+6x = (x+9)²

2x²+45+18x=x²+81+18x

x²=36

x=√36

X= 6

now

(x+6)= 12

(x+3)=9

(x+9)=15

haha sorry correct it pls

Triangle ABC has side length of 14, 8 and 10.4 what are the possible side lengths of a triangle DEF if ABC is similar to DEF

defon

Answer:

<em>DEF can have possible side lengths of 28, 16, 20.8</em>

Step-by-step explanation:

<u>Triangle Similarity</u>

If the three sides of two triangles have the same proportion, the triangles are similar (SSS theorem).

Triangle ABC has side lengths of 14, 8, and 10.4.

Any other triangle whose side lengths are the same lengths of ABC multiplied by a constant scale factor is similar to ABC.

For example, select scale factor 2. Thus, the triangle of side lengths 2*14=28, 2*8=16, and 2*10.4=20.8 is similar:

DEF can have possible side lengths of 28, 16, 20.8

Any other scale factor will do.

After a storm, two street lights with the same length are leaning against each

Ray Of Light [21]

Answer:

c = 4.79 feet

Step-by-step explanation:

Given question is incomplete without a picture; find the question with the attachment.

Two poles AD and DB of same length are leaning against each other.

Distance between the poles (AB) = 45 feet

m(∠ADB) = 180°- (60 + 50)°

= 70°

By sine rule,

$\frac{sin50}{AD}=\frac{sin70}{45}=\frac{sin60}{DB}$

$AD=\frac{45\times (sin50)}{sin70}$

= 36.68 ft

Similarly,

DB = $\frac{45\times sin60}{sin70}$

= 41.47 ft

Now c = DB - AD

= 41.47 - 36.68

= 4.79 feet
