5y - 16 + 3y + 20 = 180 degrees
Combine like terms on the left side
8y + 4 = 180
Subtract 4 from both sides.
8y = 176
Divide both sides by 8
y = 22
Plug 22 into y for each angle.
3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees
5y - 16 = 5(22) - 16 = 110 - 16 = 94
The angle opposite 5y - 16 also equals 94 because they are vertical angles.
The angle opposite of 3y + 20 also equals 86 because they are vertical angles
Answer:
ARE ≅ ΔARC
By rule - SSS Congruence Postulate
Step-by-step explanation:
We are given that in the two triangles ARE and ARC.
Sides AE ≅ AC and RE ≅ RC
Moreover, they have AR as their common side.
<em>So, we get that, in ΔARE and ΔARC, all the three corresponding sides are equal.</em>
Thus, by the SSS Congruence Postulate, ΔARE ≅ ΔARC.
