<h2>
</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- a straight line contains 180°
- a triangle contains 180°
<h3>let's solve:</h3>
equation for x
according to the question
110°+x=180°
x=180°-110°
x=70°
equation for y
according to the question
equation for z
according to the question
90°+x+z=180°
90°+70°+z=180° (since x=70°)
160°+z=180°
z=180°-160°
z=20°

Step-by-step explanation:
2) a= -3/8 and b= -5/3
a×b= b×a
<u>-3</u><u> </u>× <u> </u><u>-5</u><u> </u> = <u> </u><u>-5</u><u> </u> × <u> </u><u>-3</u><u> </u>
8. 3. 3. 8
<u> </u><u>1</u><u>5</u><u> </u> = <u> </u><u>1</u><u>5</u><u> </u>

3)a=8/11 and b= -6/11
a×b=b×a
<u> </u><u>8</u><u> </u> × <u> </u><u>-6</u><u> </u> = <u>-6</u><u> </u> × <u> </u><u>8</u><u> </u>

4) a= -9/15 and b= -7/2
a×b=b×a
<u> </u><u>-9</u><u> </u> × <u> </u><u>-7</u><u> </u> = <u> </u><u>-7</u><u> </u> × <u> </u><u>-9</u><u> </u>
