Answer:
Step-by-step explanation:
Given
Required
Determine the length of c
First, we calculate C (the third angle of the triangle).
Using Sine's law, we make use of:
By substituting values, we have:
Cross multiply
Make c the subject
approximated
0
The determinant of this matrix is zero (0).
the answer is a. y=-2x-5
a+3b
3a+4b-2a-b
=3a-2a+4b-b
=a+3b
Do you have any answer choices?
I mean one awnser could be
x divided by 2-5
