Answer:
(0,6)
Step-by-step explanation:
The given system of equations is

and

We substitute the first equation into the second equation to get:

We expand to get:

We group similar terms to get:



Put x=0 in to the first equation to get:

Therefore the solution is (0,6)
RT = RS + ST
8x - 43 = 2x - 4 + 4x - 1
8x - 43 = 6x - 5
8x - 6x = -5 + 43
2x = 38
x = 38/2
x = 19
QS = 2RS = 2(2x-4) = 2(2*19-4) = 2*34 = 68

Yo sup??
by angle sum property we know that the sum of all angles in a triangle is 180
let the unknown angle be x
then,
x+60+90=180
x=180-150
x=30
Hope this helps
