Question

WORK REQUIRED: Find the value of x. M L (10x + 20° N

Answer 1

Let's begin by listing out the information given to us:

This is an equilateral triangle; this means that all the angles in the triangle are equal

The sum of angles in a triangle is 180 degrees

We calculate x thus:

`\begin{gathered} (10x+20)=180 \\ \text{Subtrract 20 from both sides, we have:} \\ 10x+20-20=180-20 \\ 10x=160 \\ \text{Divide both sides by 10, we have:} \\ (10x)/(10)=(160)/(10) \\ x=16 \end{gathered}`
