Answer:

a. sine

Step-by-step explanation:

As it can be seen from the figure, triangle ABC is the right-angled triangle with Angle C is equal to 90 degree.

In a right-angled triangle, there is a formula as following:

<em>+) sine (an acute angle) = (length of its opposite side)/ hypotenuse</em>

In the figure, angle B and length of the hypotenuse are given.

As x is the length of AC and AC is the opposite side to angle B

=> So that we can use sine to find x

Sara says the △KLM is a right triangle. Is she correct? Explain

Olegator [25]

well, we don't know, however we know from the pythagorean theorem that the square of the two perpendicular legs added together give the slanted leg square, or namely that a² + b² = c², let's see, hmmm say a = 11in and b = 14in

$\textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2 \qquad \begin{cases} c=\stackrel{hypotenuse}{15}\\ a=\stackrel{adjacent}{11}\\ b=\stackrel{opposite}{14}\\ \end{cases}~\hfill 15^2=11^2+14^2 \\\\\\ 225=121+196\implies 225\ne 317~~\bigotimes~\hfill \begin{array}{llll} \textit{they're not equal}\\ \measuredangle L\textit{ is not a right-angle}\\ \textit{therefore }\triangle KLM\\ \textit{is not a right triangle} \end{array}$
