Answer:
meters
Step-by-step explanation:
Let's take climbing down as "negative" and climbing up as "positive". Now, we can simply use the numbers and signs to find the change in elevation.
- meters down means
- meters up means
So, now we have:
<u>Eric's elevation changed meters above. So after the 2 moves, he is up by meters.</u>
4 is 18 because 6x3 is 18
Step-by-step explanation:
Exterior angle BOA = 250°
Interior angle BOA = 360°- 250° = 110°
Now,
(A) BDA = interior angle BOA / 2 = 55°( Property of circles)
(B) From the figure, we observe that AOBC is a cyclic quadrilateral (i.e. sum of opposite angles is 180°).
Therefore, BCA + BOA = 180°
BCA = 180° - 110° = 70°
