Answer:
D) 82 units
Step-by-step explanation:
ΔBCD ≅ ΔEFG
In congruent triangles, corresponding parts are congruent
BD = EG
4x - 9 = 2x + 15
4x - 9 -2x = 15
2x - 9 = 15
2x = 15 +9
2x = 24
x = 24/2
x = 12
EG = 2x + 15 = 2*12 + 15
= 24 + 15
EG = 39 units
FE = CB = 17 units
Perimeter of ΔEFG = FE + EG + GF
= 17 + 39 + 26
= 82 units
Answer:
x=2
Step-by-step explanation:
First, subtract four on both sides and then divide both sides by 2 to get x=2.
2x+4=8
<em>-4 -4</em>
2x=4
<em>÷ 2 ÷2 </em>
<u>x=2</u>
All you have to do is find the length of the sides using the distance formula and then add the lengths together to find the perimeter
Answer:
51+x-5+y-6=180
x+y=180-51+5+6
X+y=140
Answer x=77 y=63
(those 2 lines with the arrows are perpendicular so their angles are the same 72° and (x-5)=77-5= 72°)
