Answer:
(1)x=3, y=2
(2)x=19, y=31
Step-by-step explanation:
(1)
4x-3(x-1)=6
4x-3x+3=6
x+3=6
x=3
(2)
.76x+3.68y=128.52
x+y=50
.76x+3.68(50-x)=128.52
.76x+184-3.68x=128.52
.76x-3.68=-55.48
-2.92x=-55.48
x=19
19+y=50
y=31
This took so much work.... I hope I helped you well.

sin(angle) = 65/80
angle = 54.34deg
h( x ) = ( x + 1 )^2 - 4 x(h)×(÷×1)^2-4
4 - 5 = -1
