Answer:
-9/10 =r
Step-by-step explanation:
7/10=r-(-8/5)
Subtracting a negative is like adding
7/10=r+(8/5)
Subtract 8/5 from each side
7/10 - 8/5=r+(8/5) - 8/5
7/10 - 8/5 = r
Get a common denominator
7/10 - 16/10 = r
-9/10 =r

Answer:
∠x = 78
Step-by-step explanation:
∠y + ∠1 = 180
=> 125 + ∠1 = 180
=> ∠1 = 180 - 125
=> ∠1 = 55
∠z + ∠2 = 360
=> 313 + ∠2 = 360
=> ∠2 = 360-313
=> ∠2 = 47
∠1 + ∠2 + ∠x = 180
=> 55 + 47 + ∠x = 180
=> ∠x = 180 - 55 - 47
=> ∠x = 78
