they are giving you the answer AB=AC, so what that means is that the angles are congruent to each other so if angle AC=15 and angle DC=5 all the angles will be the same.
The constant is 36
because direct variation y/x
the answer for 135 times 12 is 1620
<span><span>27100</span>(60)=<span>815</span>=16<span>15</span></span>
The 16 is how many minutes you have. If you were not given the seconds, we would have to say that we have a remainder of (1/5) of a minute. Since 1 minute is (1/60), one-fifth of that is (1/300). Now we would need to see how many seconds that gives us. 1 second is (1/3600) of a degree, so we would need to divide (1/300) by (1/3600). Doing this gives us:
<span><span><span>1300</span>÷<span>13600</span>=<span>1300</span>(3600)=12</span></span>
