Answer:
x = 7
Step-by-step explanation:
The 3 angles in a triangle sum to 180°
sum the 3 angles and equate to 180
90 + 8x + 4x + 6 = 180 , that is
12x + 96 = 180 ( subtract 96 from both sides )
12x = 84 ( divide both sides by 12 )
X = 7
180=90+4x+6+8x
84=12x
7=x
(5x^2)/(y^3)
The 2 triangles have the same circomfronce but different area
Hope it will help you a lot.
