Answer:
z = 105°
Step-by-step explanation:
See attachment.
1. The angle z plus 105° is equal to 180°, the straight line. Z must therefore be = 105°
2. Angles z and (15x + 45°) must be equal to 190°.
x is therefore equal to 4.
Multiply the numerator and denominator by the same #.
So:
27/81 x 2 = 54/163
27/81 x 3 = 81/244
Or, simplify:
<span>27/81 / 3 = 3/9 ......... = 1/3</span>
The answer to that would be B
Answer:
180
Step-by-step explanation:
The slope is -3/1 so to find other points, go to (2,-1) and go down 3, over 1.
