Answer:
a, b and d
Step-by-step explanation:
Answer:
The small triangle has a long leg of 8. The triangle area formula is used to derive this. Now, there can be a ration equation.
10/4 = x/8
x = 20
Now use the formula.
A=1/2bh
A=1/2(10*20)
A=100
Area of DEF is 100 m^2.
Work:
1) 11y - 3 = 13x
2) 11y = 13x + 3
3) y = 13/11x + 3/11
