Answer:
what does DBA mean (sorry dont knowhow to comment)
Step-by-step explanation:
Let the first angle be A and the second be B.
Complementary angles add up to 90° so:
A + B = 90
We are also told:
A = 6 + 3B; substituting this into the first equation:
6 + 3B + B = 90
B = 21°
A = 6 + 3(21)
A = 69°
Answer:
The slope is 
, or 2 over 5.
Step-by-step explanation:
Slope = rise over run
Rise is 2
Run is 5
Slope is 2 over 5
Answer:
(6, 80)
Step-by-step explanation:
First, should mark your y intercepts, which are +20 and +50 on your y axis.
Next, you must know how to use rise over run.
10 = 10/1 and 5 = 5/1
If you have a graph, you can use it for this step:
Next, you rise up 10 then go right 1 because it is positive, and do the same thing over and over again for your first equation. For your next equation, you go up 5 and right 1 since it is also positive.
