Answer:

((\frac{2}{3})^0)^{-3}=1

Step-by-step explanation:

We need to find the value of ((\frac{2}{3})^0)^{-3}

Solving:

We know, (a^b)^n = a^{b*n}

((\frac{2}{3})^{0*-3})

(\frac{2}{3})^0

a^0 = 1

so,

(\frac{2}{3})^0=1

So, the value of ((\frac{2}{3})^0)^{-3}=1

In ΔLMN, n = 92 inches, ∠N=46° and ∠L=11°. Find the length of l, to the nearest inch.
Vilka [71]

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 \\
