Answer:

24 inches

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.

Sine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:

\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}

In triangle LMN:

We can find the length of l using sine rule:

\frac{l}{sinL}=\frac{n}{sinN}  \\\\substituting:\\\\\frac{l}{sin(11)}=\frac{92}{sin(46)}  \\\\l=\frac{92}{sin(46)}*sin(11)\\\\k=24\ inches \\

Law of cosines.Anyone good in Trigonometry?​
marin [14]

Answer:

c=11.8\ units

Step-by-step explanation:

we know that

The formula of law of cosines is equal to

c^2=a^2+b^2-2(a)(b)cos(C)

where

a, b and c are sides. C is the angle opposite side c

In this problem we have

a=3\ units\\b=10\ units

C=120^o

substitute the given values

c^2=3^2+10^2-2(3)(10)cos(120^o)

c^2=109-(60)cos(120^o)

c^2=109-(60)(-0.5))

c^2=109+30

c^2=139

c=11.8\ units
