Answer:

(a) 11.

(b) 5.

Step-by-step explanation:

(a)√124:

11*11 = 121 so an estimate is 11.

(b) ∛124

5*5*5 = 125

Answer:

x=58, m<DCB=56°

Step-by-step explanation:

Ok the sum of those two angles should equal 180 degrees so,

2x+8+x-2=180

solve the equation

3x+6=180

3x=174

x= 58

M<DCB=x-2--> 58-2=56

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 \\

I need some help. Thanks! ​

Simplified to its simplest form, your answer would be 20%. Since there are 30 students in total, and 6 of them are male sophomores, you would have 6/30. This can be simplified down to 2/10 and even further to 1/5. In decimals, this becomes 0.2, which as a percent becomes 20%.
