Answer:c=57°
Step-by-step explanation:
Explanation:
It is convenient to regroup the numbers, and adjust two of them to "make a ten".
= 13 + 17 + 19 . . . . rearrange (swap the order of 17 and 19)
= (10 + 3) + (-3 + 20) + 19 . . . . "make a ten" by adding or subtracting a small number. Here, those adjustments cancel—which is the point of doing it.
= 10 + 20 + 19
= 30 + 19
= 49
Car B travels 10 more miles per hour than Car A, The line B intersects at 50, While line A intersects at 40 when they hit 1 hour! I Like this Math! Bring me back to this!!!
62 because 90 minus 15, minus 13, is equal to 62
