Question

M and N are supplementary. The measure of M is (9x-10) and the measure of n is (6x +100). Solve for x

Answer 1

Answer:

The value of $x$ is $6$.

Step-by-step explanation:

It is given that $M$ and $N$ are supplementary.

So, its expression is given by, $M+N=180\textdegree$

It is given that measure of $M$ and $N$ is,

$\begin{aligned}M&=(9x-10)\\N&=(6x+100)\end{aligned}$

Substituting values in the expression,

$\begin{aligned}M+N&=180\textdegree\\(9x-10)+(6x+100)&=180\textdegree\\15x&=90\textdegree\\x&=6\end{aligned}$
