To find: To determine whether the each
Answer to Problem 5CYU
We will use sine rule in the beginning because one angle and its opposite side is given and there is other side given.
In triangle ABC
So side AB= c= 6.9
Angle
And Angle
Explanation of Solution
Given information:
The length of two sides of triangle ABC and one angle.
AC= b = 8
BC= a =12
∠BAC=
Calculation:
So we will use sine rule in the beginning because one angle and its opposite side is given and there is other side given.
To find the angle, we use the sine formula for any triangle:
Since the sum of the angles of any triangle is
So
In triangle ABC
So side AB= c= 6.9
Angle
And Angle
