Answer: h (B1 + B2/2
Step-by-step explanation:
A and B would be 90 degrees because the angle between B anc C is 90
To find the slope of the line containing the pair of points, subtract y2 to y1 and divide x2-x1.
y2-y1
--------
x2-x1
The domain is all the ones under the x and the range are the numbers under the y (that goes fo any question like that)
Answer:
Step-by-step explanation:
<u>We have similar triangles here.</u>
- BC║DE, AB║AD and AC║AE ⇒ ΔADE ~ ΔABC
<u>The ratio of corresponding sides of similar triangles is same:</u>
- BC/DE = AC/AE
- BC / 2 = 30/3
- BC / 2 = 10
- BC = 2*10
- BC = 20 m
