The mass of b equals the mass of d so
24(10-x)=6(x+15)
240-24x=6x+90
30x=150
x=5
mass of d is 6(5+15)=6*20=120
mass of c=180-mas of d=180-120=60°
Answer: (3,6)
Rewrite in vertex form and use this form to find the vertex (h,k)
The Y intercept is (0,5)
The X intercept is (0,-10)
Answer: 10
Step-by-step explanation:
You times 4 and 5 then you divide in half because it is a triangle
If you need an equation it is -3.4x=21.5
You simply divide both sides by -3.4 to get x=-6.32
if that's not right then just get on a calculator and calculate by doing what I said to divide
