Answer:
80%
Step-by-step explanation:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((36 - 20) / 20) * 100 = 80 %
Answer:
x=10
Step-by-step explanation:
For number 19.
The equation you get is:
X+2=6(2) this is because 5x2=10, so you have to do the same here.
so, X+2=12
-2 from both sides and you get
x=10
Answer:x greater than -9
Step-by-step explanation:
Answer:
7. 7.8
Step-by-step explanation:
We can use Tan of this angle to find the missing side (in this case, the side adjacent to the angle measuring 57°)
Tan A = (opposite side)/(adjacent side)
Tan 57° = 12/x
solve for x
x(Tan 57°) = 12
x = 12/(Tan 57°)
x = 7.8 (rounded to the nearest tenth)
