Answer:
17.3 cm
Step-by-step explanation:
(refer to the attached for reference)
since the given triangle is a right triangle (i.e with one of the angles being 90 deg), we can use trigonometry to determine the missing side.
In our case, we are given ∠ABC = 68° and the length of its adjacent side AB = 7 cm.
From trigonometry, the following relationship may be formed:
tan (68°) = opposite length / adjacent length
tan (68°) = AC / AB
tan (68°) = AC / 7 (multiply both sides by 7)
7 tan (68°) = AC (rearrange)
AC = 7 tan (68°) (solve using calculator)
AC = 17.3256
AC = 17.3 cm (1 dec pl)
Answer: QS= 4.93
Step-by-step explanation: because they’re asking you to find QS which is opposite to your angle 39and we have the hypotenuse so we can use sine(39)=x/8.
Sin(39)=x/8
Multiply eight both side
8(sin(39))=x
4.93=x
X=4.93
The diameter multiplied by \pi
or the radius multiplied by 2 then by \pi
