I think the answer is c 90 percent chance
Answer:
B
Step-by-step explanation:
The angle that has tan 5 / 12 is ∠ABC so A is not the answer. The angle that has cos 5 / 13 is ∠BAC so B is the answer.
Answer:
The two numbers are 31 and 19
Step-by-step explanation:
Let x and y be the numbers
x+y = 50
x-y = 12
Add the two equations together
x+y = 50
x-y = 12
-----------------
2x +0y = 62
Divide by 2
2x/2 = 62/2
x = 31
Now find y
31+y = 50
Subtract 31
y = 50-31
y = 19
Answer:
1
Step-by-step explanation:
12x+x+4=17
13x=17-4
