Answer:
in triangle BCD
relationship between base and hypotenuse is given by cos angle
cos 71=b/h
cos71=BD/BC
cos71=67/x
x=67/cos71=205.8ft.
the length of BC to the nearest tenth of a foot is 206ft.
Answer:
A reflection in the x-axis.
Step-by-step explanation:
The first graph passes through the point (0,1) and (1,3).
The second graph passes through (0,-1) and (1,-3).
We can observe that the y-coordinates of the first graph were negated to obtain the second graph.
That is;
This is the mapping for the reflection in the x-axis.
Well, the simplest form is
. Other fractions are
etc.
Do simplifications and amplifications to reach one from another.
