U is 50 because supplementary 180-130=50
And so knowing that now
50+65+x=180 (because all triangles are equal to 180)
Add 50 and 65
115 +x=180
Subtract 115 on both sides
X=65
The answer is A
Answer:
61
Step-by-step explanation:
80+39=119
180-119=61
Answer:
see the explanation
Step-by-step explanation:
we have
----> equation A
---> equation B
we know that
The solution of the system of equations by graphing is the intersection point both graphs
The solution of the system is the point (-2,-5)
therefore
The point (-2,-5) indicate on the coordinate plane the intersection point both lines ( a common point for both lines)
