​

Answer 1

Answer:

To draw a Equilateral Triangle you have to fast take the measurement with the scale then draw any line on another side and cut the measurement then draw 60 degree angle on one point of that line segment and then cut the same measurement from the three side and then it will be equilateral triangle which 4.5 cm length

Answer 2

Step-by-step explanation:

Answer:

Let the unknown number be x.

According to question,

\begin{gathered} \dashrightarrow \sf \frac{5}{12} \div x = \frac{ - 35}{18} \\ \\ \end{gathered}

\begin{gathered} \dashrightarrow \sf \frac{5}{12} \times \frac{1}{x} = \frac{ - 35}{18} \\ \\ \end{gathered}

By Cross Multiplication :

\begin{gathered}\dashrightarrow \sf12x \times ( - 35) = 5\times 18 \\ \\ \end{gathered}

⇢12x×(−35)=5×18

\begin{gathered}\dashrightarrow \sf - 420x = 90 \\ \\ \end{gathered}

⇢−420x=90

Hence, Option (d)-3/14 is correct.
