Answer:
Step-by-step explanation:
Answer:
The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board
step 1:
Find the area of the square game board
"A=b^{2}"
we have
b=20cm
"substitute"
A=20^{2}
=400cm²
step 2:
Find the probability
P=314/400
=0.785
=0.785 x 100
=78.5%
Answer:

Step-by-step explanation:
Answer:
5
Step-by-step explanation:
by pythagoras theorem
(hyp)^2=(leg1)^2+(leg2)^2
the hypotenuse is the side opposite to 90 degree (BC=13)
AC=leg 1 = 12
13^2=12^2 + leg 2^2
169=144+ leg 2^2
leg2 ^2=169-144
leg2^2= 25
leg2= root 25
leg2=5
