This one is the Law of Sines again.
The Law of Sines relies on the standard labeling of triangle ABC with vertices A, B, and C and respective opposite sides of a, b and c. Then
Here we have A=150 degrees (opposite side a), b= 10 cm and B = 12 degrees. We seek a.
So we need the first equation of the Law of Sines:
Answer:
x = 2.6
Step-by-step explanation:
Here we have that line l is the bisector of segment PQ.
According to the definition of bisector, this means that line l cuts the segment PQ into two parts of equal length.
This means that the length of PM must be equal to the length of MQ. So we can write:
Now we have to solve the equation to find x. First, we add +7 on both sides:
Now we add +2x on both sides:
And therefore,
