Answer:

∠ A'OB' = 79°

Step-by-step explanation:

∠ AOC = ∠ C'OA' = 35° ( vertical angles )

BOB' is a straight angle , thus

∠ COB' = 180° - (79 + 35)° = 180° - 114° = 66°

C'OC is a straight angle, thus

∠ A'OB' = 180° - (66 + 35)° = 180° - 101° = 79°

Solve the system of equations. <br><br> y=x+5 <br><br> y=-x+7

spin [16.1K]

Answer:

(1,6)

x = 1, y = 6

See attachment for the graph

Step-by-step explanation:

y=x+5

y=-x+7

Using the elimination process

y=x+5

- y=-x+7

----------------

0=2x-2

2=2x

1=x

x=1

Substitute x = 1

y = x + 5

y = 1 + 5

y = 6
