Answer:
x = 52, y = 137 degrees.
Step-by-step explanation:
x = 180 - 90 - 38
x = 52 degrees (as there is 180 degrees in a triangle).
As they are the same side inner angles between 2 parallel lines:
x + (y - 9) = 180
52 + y - 9 = 180
y = 180 - 52 + 9
y = 137 degrees.
97% because that is the average of the three test scores.
Answer:
A) (i) a = 95° (180 - 85), b = 85° (180 - 95), c = 85° (180 - 95), d = 95° (180 - 85)
A) (ii) a = 103° (180 - 77), b = 77° (180 - 103), c = 103° (180 - 77), d = 77° (180 - 103)
B) (i) 95 + 85 + 85 + 95 = 360°
B (ii) 103 + 77 + 103 + 77 = 360°
Tip: Angles on a straight line add to 180°
Hope this helps!
Answer:
3/10 x 100 = 30.00
Step-by-step explanation:
Three tenths written as a fraction is 3/10. You can also write it as a decimal by simply dividing 3 by 10 which is 0.30.
If you multiply 0.30 with 100 you will see that you will get 30
