Step-by-step explanation:
Acute Isosceles Triangle
Side a = 1
Side b = 1
Side c = 0.51764
Angle ∠A = 75° = 1.309 rad = 5/12π
Angle ∠B = 75° = 1.309 rad = 5/12π
Angle ∠C = 30° = 0.5236 rad = π/6
C=30°B=75°A=75°b=1a=1c=0.518
Area = 0.25
Perimeter p = 2.51764
Semiperimeter s = 1.25882
Height ha = 0.5
Height hb = 0.5
Height hc = 0.96593
Median ma = 0.61966
Median mb = 0.61966
Median mc = 0.96593
Inradius r = 0.1986
Circumradius R = 0.51764
Vertex coordinates: A[0, 0] B[0.51764, 0] C[0.25882, 0.96593]
Centroid: [0.25882, 0.32198]
Inscribed Circle Center: [0.25882, 0.1986]
Circumscribed Circle Center: [0.25882, 0.44829]

Answer:
x= 0
y= -3
Step-by-step explanation:
6x-5y=15
substitution...
6(y+3)-5y=15
6y+18-5y=15
y+18=15
-18 -18
y= -3
substitution again...
6x-5(-3)=15
6x+15=15
-15 -15
6x=0
/6 /6
x= 0
