Answer:

Option C is incorrect

Step-by-step explanation:

Considering the congruent triangle

$Side LJ = Side GI\\Side HI = Side KL\\Side GH = Side KJ\\Angle G =Angle J = 70 Degrees\\Angle I = Angle L = 30 Degrees\\Angle H = Angle K = 90 Degrees\\$

Thus option C is incorrect

Sin theata=3/5, then cos theata= ?

Elena-2011 [213]

$\bf sin(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{hypotenuse}{5}}\impliedby \textit{let's find the \underline{adjacent side}}
\\\\\\
\textit{using the pythagorean theorem}
\\\\
c^2=a^2+b^2\implies \sqrt{c^2-b^2}=a
\qquad
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
\sqrt{5^2-3^2}=a\implies \pm\sqrt{25-9}=a\implies \pm 4=a
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
~\hfill cos(\theta )=\cfrac{\stackrel{adjacent}{\pm 4}}{\stackrel{hypotenuse}{5}}~\hfill$

What is the measure of one exterior angle of a regular hexagon?<br>a. 60<br>b.72<br>c. 90

Molodets [167]

To find the exterior angle measure we would use the following formula:
$\frac{360~degrees }{number ~of ~sides}$
A regular hexagon has 6 sides so we divide:
360/6 which equals 60
So our final answer would be A. 60
