It’s - ( - 3 ) because a negative times a negative equals a positive so it wouldn’t be - ( 3 ) because it would turn into a negative number and - ( - 3 ) would be positive

Solve for the missing angle. Round to the nearest hundredth.<br> 18<br> ?<br> 13<br> ? =<br> degrees
skad [1K]

Answer:

\theta \:=43.76^{\circ \:\:}

Step-by-step explanation:

The right triangle has the hypotenuse = 18

Let 'Ф' be the missing angle

we know that

cos Ф = adjacent/hypotenuse

Here,

  • The adjacent to Ф = 13
  • The hypotenuse = 18

so

cos Ф = adjacent/hypotenuse

cos\:\theta \:=\frac{13}{18}

\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)

   =43.76^{\circ \:}

Therefore, the missing angle is:

\theta \:=43.76^{\circ \:\:}
