3. Angles X and Y have a sum of 159 degrees. Angle X is 43 degrees smaller than angle Y.

Lesechka [4]

$\underline{\underline{\large\bf{Solution:-}}}\\$

$\longrightarrow$ Since angle X and Y have a sum of 159

$\implies \bf Y + X= 159 \_\_\_\_(1)$

$\longrightarrow$ Since X is 43 degrees smaller than Y , so subtracting X from Y would give 43 , therefore equation will be written as -

$\implies \bf Y - X = 43 \_\_\_\_(2)$

<u>Adding Equation (1) and (2) </u>

$\begin{gathered}\\\implies\quad \sf Y+X+Y-X = 159+43 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf Y+Y + X-X = 202 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 2Y = 202 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf Y = \frac{202}{2} \\\end{gathered}$

$\begin{gathered}\\\implies\quad \boxed{\sf {Y = 101 }} \\\end{gathered}$

<u>Putting Y in eq (1)</u>

$\begin{gathered}\\\implies\quad \sf X + 101 = 153 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf X = 153-101 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \boxed{\sf{ X = 52 }}\\\end{gathered}$
