Rini used a stick to draw a right triangle in the ground. The hypotenuse of her triangle is 24 inches and one of the legs is 12
Mademuasel [1]
Use the pythagorean theorem A² + B² = C²

A and B are legs and C is the hypotenuse 

so-    A² + 12² = 24²      A² + 144 = 576  
                                           -144     -144

                                   A² = 432          then you have to take the square root 
                                                           of each side 

so-      A = √432    or aprox. 20.78

Solve for x. Leave your answer in simplest radical form.
strojnjashka [21]

There are two Right angled triangles in the given figure, with two missing sides, let's name the other missing side be " y "

According to Pythagoras theorem,

\boxed{ \large \boxed{h {}^{2}  =  {b}^{2} + p{}^{2}  }}

note :

  • p = perpendicular / opposite side
  • b = base / adjacent side
  • h = hypotenuse

let's solve for " y² " first ( square of other missing side )

➢ \:  \:  {y}^{2}  =  {8}^{2}  + 3 {}^{2}

➢ \:  \:  {y}^{2}  = 64 + 9

➢ \:  \:  {y}^{2}  = 73

now let's solve for " x " , by using pythagorous theorem

➢ \:  \:  {x}^{2}  =  {y}^{2}  +  {6}^{2}

➢ \:  \:  {x}^{2}  = 73 + 36

➢ \:  \:x {}^{2}  =  109

➢ \:  \: x =  \sqrt{109}

Approximate :

➢ \:  \: 10.44 \:  \: units

Which statements about the function f are true? Check all that apply.
goblinko [34]

Answer:

The domain (or input values) of a continuous line is all real numbers

The range (or output values) of a continuous line is all real numbers

f(2) =4

Step-by-step explanation:

The domain (or input values) of a continuous line is all real numbers

x can be positive and negative

The range (or output values) of a continuous line is all real numbers

y can be positive and negative

f(2) is the value of y at x =2

f(2) =4

g(2) = 1/2(2) +3
