Answer:
A x =30
Step-by-step explanation:
(y+x) and (y-x) make a straight line so they add to 180 degrees
(y+x) + (y-x) = 180
Combine like terms
y+y+x-x=180
2y=180
Divide by 2
2y/2 = 180/2
y= 90
(y+x) and 2x make a straight line so they add to 180 degrees
y+x+2x = 180
Combine like terms
y+3x = 180
Since we know y we can substitute it in
90+3x = 180
Subtract 90 from each side
90-90+3x= 180-90
3x = 90
Divide by 3
3x/3 = 90/3
x= 30

Answer:
84% decrease
Step-by-step explanation:
500-80 = 420
420/500= 0.84
0.84 x 100 = 84 percent decrease
btw you divide 420 by 500 and not by 80 because you are going FROM 500 TO 80.
Answer:
B
Step-by-step explanation:
Answer:
This is an Obtuse triangle.
Step-by-step explanation:
A Equilateral Triangle is a triangle where all sides are equal. Here all sides are different so it is not an Equilateral Triangle.
Isosceles triangle is a triangle that has 2 sides that are equal. Here all sides are different therefore this is not an Isosceles triangle.
A right angled triangle is a triangle whose sides satisfy the following equality.
Lets say A triangle has sides a, b and c. Where c is the highest value.
Then,
Lets substitute the values to the above equation to see whether it the triangle we are given satisfies the above equality,
= =
Therefore, ≠ = ≤
Therefore, This is an Obtuse triangle.
