(Observed data - Accepted standard) divided by the accepted standard. Then all of that is multiplied by 100.
( ( O - A ) / A) * 100
Answer:
a = 5√7
Step-by-step explanation:
Sides of a right triangle follow the Pythagoras theorem,
By Pythagoras theorem,
(AB)² = (BC)² + (AC)²
c² = a² + b²
If b = 9 and c = 16,
(16)² = a² + 9²
256 = a² + 81
a² = 256 - 81
a = √175
a = 5√7
Therefore, measure of third side a = 5√7
Given:
Volume of the cone = π r² h/3
radius of the cone is half the radius of the cylinder ⇒ r/2
height of the cone is equal to the radius of the cylinder. ⇒ r
V = 3.14 * (r/2)² * r/3
V = 3.14 * r²/4 * r/3
V = 3.14r³ / 12
So you know that angle I is verticle angles to the 60 degrees angle
And you known that the verticloe angle to 20 is an important part
Then you use the sum of interior angles formula
which is all the angles in the triangle should add up to 180
20 + 60 + m< HEI = 180
80 + m< HEI = 180
-80 -80
m< HEI = 100
I believe the measure of the angle is 100, I hope it makes sense too!
Answer:
x = 7
T(7, 3)
Step-by-step explanation:
The slope of the line is the same everywhere, so the ratio of y-differences to x-differences is constant.
Differences between R and S:
S -R = (-1, -1) -(-5, -3) = (-1+5, -1+3) = (4, 2)
T -R = (x, 3) -(-5, -3) = (x+5, 3+3) = (x+5, 6)
Then the ratios of y-differences to x-differences are ...
2/4 = 6/(x+5)
2(x+5) = 4(6) . . . . cross multiply
2x +10 = 24 . . . . . simplify
2x = 14 . . . . . . . . subtract 10
x = 7 . . . . . . . . . . divide by 2
Point T is (7, 3). . . . . . . . (x=7)
