Answer:
9 to 2 = 2+4+3=9 2 picks all together you have 9 marbles and you have 2 picks this will give you a ratio of 9 to 2
Answer:
28.9°
Step-by-step explanation:
The golfer, hole, and spectator form a triangle. Let ABC be the triangle and let the angle the spectator has between the golfer and the hole be A = 110°, the angle the golfer has between the spectator and the hole be B, and the angle the hole has between the golfer and the spectator be C. Let the angle between the golfer and the hole be a = 200 yards, the distance between the spectator and the hole be b and the distance between the golfer and the spectator be c = 140 yards,
Using the sine rule for the triangle, we find angle C.
So, a/sinA = b/SinB = c/SinC
So, a/sinA = c/sinC
sinC = csinA/a
C = sin⁻¹(csinA/a)
Substituting the values of the variables into the equation, we have
C = sin⁻¹(csinA/a)
C = sin⁻¹( 140sin110°/200)
C = sin⁻¹( 7 × 0.9397/10)
C = sin⁻¹(6.5778/10)
C = sin⁻¹(0.65778)
C = 41.13°
We know that A + B + C = 180° (sum of angles in a triangle)
And since the angle, the golfer has between the spectator and the hole be B
So, B = 180° - (A + C)
B = 180° - (110° + 41.13°)
B = 180° - 151.13°
B = 28.87°
B ≅ 28.9°
Answer:
20
Step-by-step explanation:
Answer:
Step-by-step explanation:
use the point slope formula
y - y1 = m(x -x1)
where "m" is an undefined slope
and plug in the given point (4,7) it's form is (x1,y1)
y-7 = m(x - 4)
y = m(x - 4 ) + 7
