Answer:
x= 1/3
y = -8
Step-by-step explanation:
-2y+ y = 8 equation 1
-3x -y =7 equation 2
using equation 1 we have:
-2y+ y = 8
-y = 8
y = -8 equation 3
using equation 3 in equation 2 we have:
-3x -y=7
-3x -(-8)=7
-3x +8 =7
-3x = 7-8
-3x = -1
x= 1/3
Answer:
81/100
Step-by-step explanation:
30 + 51/100 = 81/100
3 and 2 would be 122 since 3 and the 58° are a linear pair making them add up to 180. And 3 and 2 are vertical so they would be congruent.
4 would then have to be 38 since the three angles would have to measure up to 180.
And the 1 would have to be 36 with the same reasoning as before.
