36 / 9 equals 4 so the problem is basically 10 + 4 which is 14.
The simplified expression is 17z
∠DBC = 19° since the two angles have to add up to 180, if x = 23, then 23 -4 = 19 for the right, and 7 x 23 = 161, and 161 + 19 = 180.
Answer:
x - y = 3
any values of x& y where x is three greater than y
I.E. x = 8 y = 5
Step-by-step explanation:
The answer is B
Since you know that BOD is a right angle add 12 And 15 and subtract your answer from 90
