Answer 1

By Linear pair equation,

(3α +10)+(2α-30)= 180°

3α + 10° + 2α - 30° = 180°

5α -20° = 180°

5α = 180°+20°

5α = 200°

α = 200°/5

α = 40°

$\huge\boxed{\fcolorbox{black}{</strong><strong>yell</strong><strong>ow</strong><strong>}{</strong><strong>α = 40°</strong><strong>}}$

therefore,

$\boxed{\fcolorbox{black}{yellow}{</strong><strong>4α = 4×40° = 160°</strong><strong>}}$

$\boxed{\fcolorbox{black}{yellow}{</strong><strong>(</strong><strong>3</strong><strong>α</strong><strong>+</strong><strong>1</strong><strong>0</strong><strong>)</strong><strong>=</strong><strong> </strong><strong>3</strong><strong>×</strong><strong>4</strong><strong>0</strong><strong>+</strong><strong>1</strong><strong>0</strong><strong>=</strong><strong> </strong><strong>1</strong><strong>2</strong><strong>0</strong><strong>+</strong><strong>1</strong><strong>0</strong><strong>=</strong><strong> </strong><strong>1</strong><strong>3</strong><strong>0</strong><strong>°</strong><strong> }}$

$\boxed{\fcolorbox{black}{yellow}{(2α-30)= 2×40-30= 80-30= 50° }}$
