Answer:

y = 107 x = 73 and z = 73 degrees

Step-by-step explanation:

All of the angles have to equal 360 when added together and y has to correspond to 107 then those add to 214 then you subtract that from 360 to get 146 then you split that in half to get the x and z

Answer:

x = 73, y = 107, z = 73

Step-by-step explanation:

y has a vertical angle so y = 107°

z° and x° are also vertical angles so z° = x°

To find z and x find the angle adjacent to 107°

180° - 107° = 73°

x = 73, z = 73

ad-work [718]
Let x = number of cups of ingredient B if 2 cups of ingredient A are used. Set up a proportion:  (1/2)/(1 2/5) = (2)/x. Cross multiplying we get (1/2)x = (1 2/5)(2) 
 (1/2)x = 14/5, so x = 28/5 = 5 3/5 cups.
