Answer:
Solution given:
we have
<A+<B=exterior <C[<u>s</u><u>u</u><u>m</u><u> </u><u>o</u><u>f</u><u> </u><u>t</u><u>w</u><u>o</u><u> </u><u>opposite</u><u> </u><u>interior</u><u> </u><u>angle</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>tri</u><u>angle</u><u> </u><u>is</u><u> </u><u>equal</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>exterior</u><u> </u><u>angle</u><u> </u><u>in</u><u> </u><u>a</u><u> </u><u>triangle</u><u>]</u>
<u>So</u>
3x-13+ 2x+4=116°
5x-9=116°
5x=116°+9°
x=125/5
x=25
Now
<u><</u><u>A</u><u>=</u><u>3</u><u>×</u><u>2</u><u>5</u><u>-</u><u>1</u><u>3</u><u>=</u><u>6</u><u>2</u><u>°</u>
<u><</u><u>B</u><u>=</u><u>2</u><u>×</u><u>2</u><u>5</u><u>+</u><u>4</u><u>=</u><u>5</u><u>4</u><u>°</u>
