Answer:
The solution to the given system of equations is
(
,
)
Step-by-step explanation:
Given system of equation are


To solve equation by using elimination method
Now subtracting equations (1) and (2)


_________________
5x=-16

Substitute
in equation (1)





Therefore the solution is
(
,
)
3x+2/5=7
3x+2/5=35/5
3x=35/5-2/5
3x=33/5
x=(33/5)/3
x=(33/5)/(3/1)
x=(33/5)*(1/3)
x=33/15
x=30/15+3/15=2+1/5
x=2.2
It looks like a scalene triangle but i’m not so sure
You use cos inverse and the answer is 84 degree
