Step-by-step explanation:
You need the Law of Cosines for this, namely:
where x is the missing side.
and

Answer:
x = 2
Step-by-step explanation:
Answer:
y = 4
Step-by-step explanation:
KM / 10 = KO / 16
(4y - 1) / 10 = 6y / 16
KO = 4y-1 + 2y+1 = 6y
cross-multiply:
60y = 64y - 16
-4y = -16
y = 4
Add them all around the top pointing down
Answer:
7/36
Step-by-step explanation:
1 die has 6 faces
When two dice are rolled, the total number of outcomes
= 6 × 6 = 36
The Probability of having(5) =
(1 & 4), (2 & 3) , ( 3 & 2), (4 & 1)
= 4
The probability of having (10) =
(5 & 5), (4 & 6) , ( 6 & 4)
= 3
The probability that the score on the dice is either 5 or 10.
P(5) + P(10)
= 4/36 + 3/36
= 7/36
