Finger [1]

Answer:

Step-by-step explanation:

Find the diagram attached

From the diagram;

Hypotenuse = 81.9

Angle of elevation = 65degrees

Required

The value of x (Adjacent)

Using the SOH CAH TOA identity

cos theta = adjacent/Hypotenuse

cos 65 = x/81.9

x = 81.9cos65

x = 81.9(0.4226)

x = 34.61

Hence the value of x to the nearest hundredth is 34.61

Simplify each square root expression. Describe the simplified form of the expression as rational or irrational. In your final an

expeople1 [14]

Answer:

Part 1) 11 is a rational number

Part 2) $4\sqrt{3}$ is a irrational number

Step-by-step explanation:

we know that

A <u><em>Rational Number</em></u> is a number that can be made by dividing two integers

Part 1) we have

$\sqrt{121}$

we know that

$121=11^{2}$

substitute

$\sqrt{11^{2}}=(11^{2})^{\frac{1}{2}}=(11)^{\frac{2}{2}}=11$

Is a rational number, because i can express the number 11 as the ratio of two integers (as example 11/1)

Part 2) we have

$\sqrt{48}$

we know that

$48=2^{4}(3)$

substitute

$\sqrt{2^{4}(3)}=(2^{4}(3))^{\frac{1}{2}}=4\sqrt{3}$

Is a irrational number, because cannot be expressed as the ratio of two integers
