Answer:
y=-3x+13
Step-by-step explanation:
y- 4 = -3(x - 3)
y-4=-3x+9
3x+y-13=0 this is correct answer
Triangle = 180 Degrees, so 77.
42+35+x=180
x = 77
678 cu. in.

<FCD
<SNP
SN
FC
Look at the vertex of each angle and match it to the other triangle (tri. DFC is congruent to tri. SNP) F=N, which is the vertex, D=S, C=P, DF=SN, and so on
