Answer:
B. x² - 13x + 42
Step-by-step explanation:
You do 65+90=155
then 180-155=25 to get the angle next to w
w=155
Answer:
x= 60°, y = 80°, z = 40°
Step-by-step explanation:
Look at the line substending 40° and Z°; you would see that both lines are parallel and so their angles are they the same.
Hence z= 40° { corresponding angles of parallel lines}
Similarly;
Look at the line substending 60° and x°; you would see that both lines are parallel and so their angles are they the same.
60° = x° { corresponding angles of parallel lines}
Now looking at the angle between x and y; let's call the angle between them r
And you would observe closely that r = z° = 40°{ vertically opposite angles are equal}
Note that x + r + y = 180°{ angle on a straight line}
y = 180° - ( x + r)
y = 180 - (60+40)
y = 180° - 100°
= 80°
7 over 21 . because you add 7 plus 8 plus 6 and get 21 then have 7 white shirts
Answer:
$65
Step-by-step explanation:
30% of 50 is 15, so 50+15=65.
