The area of the right triangle =

b = base = SV = 12.3
h = hight = HL = 24.6
A = area

Answer:
1.one solution is the answer
Step-by-step explanation:
#4)
cross multiply
2(8x+10) = 4 * 5x
16x + 20 = 20x
4x = 20
x = 5
48 inches cubed is the answer
X - y + x + y = 180
2x = 180
x = 90
2x - 2y = x + y
x = 3y
y = x/3
y = 90/3
y = 30
x - y = 90 - 30 = 60
x + y = 90 + 30 = 120
2x - 2y = 180 - 60 = 120
