An equilateral triangle has a side labeled 3x. The perimeter of the triangle is 99 cm.

$\underline{\underline{\frak{\qquad To\:Find :\qquad}}} \\$

The measure of the sides of the traingle = ?

$\underline{\underline{\frak{\qquad Solution :\qquad}}} \\$

An equilateral triangle has a side labeled 3x.Perimeter of an equilateral traingle = 99 cm

☯ $\underline{\boldsymbol{According\: to \:the\: Question\:now :}}\\$

$:\implies \sf Perimeter_{(of \: equilateral \: \Delta)} = 3a \\ \\ \\$

$:\implies \sf 99 = 3(3x) \\ \\ \\$

$:\implies \sf 99 = 9x\\ \\ \\$

$:\implies \sf x = \dfrac{99}{9} \\ \\ \\$

$:\implies \sf x = 11 \: cm \\ \\ \\$

$\bigstar \: \underline{\textsf{The measure of the sides of the equilateral traingle :}} \\ \\$

$\dashrightarrow\:\:\sf Side_{(of \: equilateral \: \Delta)} = 3x \\ \\ \\$

$\dashrightarrow\:\:\sf Side_{(of \: equilateral \: \Delta)} = 3(11) \\ \\ \\$

$\dashrightarrow\:\: \underline{ \boxed{\sf Side_{(of \: equilateral \: \Delta)} = 33 \: cm}} \\ \\$

$\therefore\:\underline{\textsf{The measure of the sides of the traingle is \textbf{33 cm}}}. \\ \\$

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━

$\underline{\underline{\frak{\qquad Verification :\qquad}}} \\$

$\longrightarrow\: \sf 99 = 3(3x) \\ \\ \\ \\$

$\longrightarrow\: \sf 99 = 3(3 \times 11) \\ \\ \\ \\$

$\longrightarrow\: \sf 99 = 3(33) \\ \\ \\ \\$

$\longrightarrow\: \underline{ \boxed{\sf 99 = 99}}\\ \\ \\ \\$

$\longrightarrow\: \underline{ \boxed{\sf LHS = RHS}}\\ \\ \\ \\$

$\underline{\underline{\frak{\qquad Hence, Verified\qquad}}} \\ \\$

Africans having pride in their own culture despite being ruled by people of different cultures gave them a sense of self worth.

Explanation:

The people of Africa were ruled by people of different cultures and by the people from different countries. They had a history of colonial rule where they were a colony of many countries.

But despite being ruled by people of different cultures, the people of Africa had pride in their own culture. This gave these people a sense of self worth. The Africans had pride in their own culture, in their own language and their own nation.
