Okay so under the quadrilateral section the first one is a rectangle, the next one is a square, after that it’s a rhombus, and the last one is a trapezoid. Then on the triangles section the first one is an equilateral, the middle one is isosceles, and the last one is scalene. Hope this helped!
X^4 - x^2 + 9 - (x^3 + 3x^2 + 12) =
x^4 - x^3 - 4x^2 - 3
Answer:
<em>m<A = 40 deg</em>
<em>m<B = 60 deg</em>
<em>m<C = 80 deg</em>
Step-by-step explanation:
2x + 3x + 4x = 180
9x = 180
x = 20
m<A = 2x = 2(20) = 40
m<B = 3x = 3(20) = 60
m<C = 4x = 4(20) = 80
m<A = 40 deg
m<B = 60 deg
m<C = 80 deg
Bro it’s C i just took this test lol
