Question

The measures of five angles of a hexagon are equal and the sixth measure ${100}^0$. Then the measure of each of the five angle is

• A. ${120}^0$
• B. ${124}^0$
• C. ${128}^0$
• D. ${130}^0$

Answer 1

Answer: (B)

${124}^0$

According to the problem,

5 angles of hexagon are equal .

So, let each angles be $x$ and other another is ${100}^{\circ }$

Hence,

$x+x+x+x+x+100=720$

$5x=720-100$

$x=\frac{620}{5}$

$x={124}^{\circ }$

Therefore each angles of hexagon is ${124}^{\circ }$
