Answer:84 degrees
Step-by-step explanation:
If you take 180 degrees and subtract it by 96 degrees youll get 84 degrees
96 degrees + 84 degrees = 180 degrees
Answer:
x=7 and y=4
Step-by-step explanation:
I will use the elimination method:
Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:
3x + y =25
+ + +
2x - y = 10
Simplify:
5x=35
Divide both sides by 5:
5x÷5=35÷5
Simplify:
x=7
Substitute this into either equation 1 or 2 ( I chose 1):
3(7) + y = 25
21 + y = 25
Subtract 21 from both sides and simplify to get y:
21+y-21=25-21
y=4
Therefore x=7 and y=4
Area of a circle is :
Where r is the radius.
To find r, you divide the diameter by 2
