Let's see what factors do the numbers have
do the nominator and nominator have any factors in common? no! then it can't be simplified!
Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
Answer:
Step-by-step explanation:
See attachment for complete question
Let the position of the submarine be represented with X
Given
First, we calculate angle at X.
Solving (a): Distance AX: The distance between ship A and the submarine
To do this, we apply sine formula which states
In this case:
Substitute values for AB, and
Make AX the subject
Solving (b): Distance BX: The distance between ship B and the submarine
To do this, we apply sine formula which states
In this case:
Substitute values for AB, and
Make BX the subject
