Answer:

72 / 5

Step-by-step explanation:

( 12 / 5 ) + ( 6 / 5 )

[ ( 12 / 5 ) + ( 6 / 5 ) ] / ( 1 / 4 )

Can somebody help me ???
Firlakuza [10]

Answer: to find y, simply make the equation y+82=180 since we know a straight line is 180 degrees. Solving gives us Y=98.

To find Z we can use the vertical angles property. Y is equal to 4z+14 in this property. Since we know y=98, we can say that 4z+14=98. Let’s solve again. We get Z=21.

Step-by-step explanation: AGAIN, please ask me if this doesn’t make sense. I’ll try my best to explain further. Merry christmas lkwkn
