Answer:
yes
Step-by-step explanation:
If GH║FE, then ∆DEF ~ ∆DHG.
In similar triangles, corresponding sides have the same ratios.
The ratios of corresponding sides are ...
DG/DF = DH/DE
DG/(DG + GF) = 18/(18+36)
(1/2GF)/((1/2GF +GF) = 1/3
(1/2)/(3/2) = 1/3
1/3 = 1/3
Corresponding sides are proportional. Angle D is congruent to itself, so ∆DEF ~ ∆DHG by the SAS similarity postulate. Angles DGH and DFE are therefore congruent and GH║FE.
4th option is correct: 16 R5
Answer:
D
Step-by-step explanation:
2x - 15 = 2x - 15
whatever the x we take the left and right side are the same
Hello!
First of all, let's add 50 to both sides.
x/-3=50
Now we multiply both sides by -3.
x= -150
I hope this helps!
