This equals the the area of white part / area of the entire dartboard
area of the entire board = pi * 6^2 = 36pi
area of white part = 36pi - 2^2*pi = 32pi
do required probability = 32pi / 36pi = 0.889 or 88.9 % (to nearest tenth)
or as a fraction it is 8/9
Hmmmm
This looks like homework, you sure you've read the terms of service?
Answer:
<1
Step-by-step explanation:
When an observer is at the same level with the submarine, his line of sight above the horizontal upward to the boat would form an angle called the angle of elevation.
Thus, the angle of elevation from the submarine to the boat is marked as <1. <1 is the angle of elevation from the submarine.
Answer:
∠TRS = 68°
Step-by-step explanation:
∠TRS + ∠S = 180 - 44 = 136
∠TRS = ∠S
2∠TRS = 136
∠TRS = 68
Answer:
Therefore the true statement is option b . SK > YU
Step-by-step explanation:
Given:
SA ≅ OY
AK ≅ OU
∠A = 90°
∠O = 70°
To Prove:
SK > YU
Proof:
We have,
Hinge theorem:
States that ''if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle''.
In Δ SAK and Δ YOU
SA ≅ OY
AK ≅ OU
∠ A is larger than ∠O
i.e 90 > 70
Side opposite to 90 > Side opposite to 70
∴ SK > YU ..............Proved
Therefore the true statement is option b . SK > YU
