What is the value of theta for the acute angle in a right triangle?

balu736 [363]

we are given

$sin(\theta)=cos(73)$

we have to find theta

so, firstly we can write sin in terms of cos

$sin(\theta)=cos(90-\theta)$

now, we can set it equal

$cos(90-\theta)=cos(73)$

Since, both sides are cos

so, we can set angles equal

$90-\theta=73$

now, we can solve for theta

we get

$\theta=17$ ..............Answer

Answer:

$\sf \dfrac{203}{4108}$

As a decimal = 0.05 (nearest hundredth)

Step-by-step explanation:

$\sf Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ possible \ outcomes}$

First pick:

$\sf \implies P(pink)=\dfrac{30}{80}$

As the case is NOT replaced, second pick:

$\sf \implies P(pink)=\dfrac{30-1}{80-1}=\dfrac{29}{79}$

As the case is NOT replaced, third pick:

$\sf \implies P(pink)=\dfrac{29-1}{79-1}=\dfrac{28}{78}$

Therefore,

$\sf \implies P(pink \ and \ pink \ and \ pink)=\dfrac{30}{80} \times \dfrac{29}{79} \times \dfrac{28}{78}=\dfrac{203}{4108}$

Answer as a decimal = 0.05 (nearest hundredth)
