This is Geometry. Can someone help me find the side length asked for?

The trick is to recognize a few things.

1. These are similar triangles, so the ratio of BU to BC is the same as BT to BA and UT to CA.

    \dfrac{BU}{BC}=\dfrac{BT}{BA}=\dfrac{UT}{CA}

2. BC = 2 BUs and BA = 2 BTs

This means the sides of the short triangle are half the length of the sides of the big triangle.

Put in other words, CA = 2 UT

Put into an equation x+29 = 2(x+19).

   x + 29 = 2x + 38

        –9  = x

So that means UT = 10 and CA = 20

kow [346]

Answer:

x = 4

Step-by-step explanation:

x : 8 = 2 : x \\  \frac{x}{8}  =  \frac{2}{x}  \\  \\ cross \:  \: multiple \\  {x}^{2}  = 16 \\ x =  \sqrt{16}  \\ x = 4

Help me ???? Really need the help i dont remember learning this
vlada-n [284]
Hmmmm

the 1 in 435.15 is worth 0.1 or 1/10


1/10 of 1/10 is 1/10 times 1/10 or 1/100 or 0.1/10 or 0.01/1 or 0.01

so we want one with the 1 that is 2 spaces to the right of the decimal
that is choice H
remember, when you divide by 10, move the decimal to the left 1 space

H is the answer

The areas of the squares adjacent to two sides of a right triangle are 29.2529.2529, point, 25 units^2 2 squared and 131313 unit
bonufazy [111]

Answer:

6.5 units

Step-by-step explanation:

We are given that

Two adjacent sides of right triangle

Suppose a,b and c are sides of right triangle.

a^2=29.25squared units

b^2=13square units.

Length of third side,c=x units

We have to find the length of third side of the triangle.

x^2=a^2+b^2

By using Pythagoras theorem

(Hypotenuse)^2=(Perpendicular\;side)^2+(Base)^2

x^2=29.25+13

x=\sqrt{29.25+13}

x=6.5units

Hence, the length x of the third side of the triangle=6.5 units
