Answer:
-4/3
Step-by-step explanation:
Moving from C(-4, 4) and D(5, -8) we see that x (the 'run') increases by 9 and that y (the 'rise') decreases by 12. Thus, the slope m is rise/run, or
m = -12/9 = -4/3
Answer:
x=40.375
Step-by-step explanation:
Since HYV and AYB are similar, we know that the sides in each of the triangles with have the same ratio to each of their corresponding sides.
For example, YV/YB=YH/YA.
Now we have to find the ratio of the sides which can be done using the lengths of segments YB and YV. YB=16 YV=16+22=38 38/16=2.375
2.375 is our ratio.
Next we are going to find the length of YH so we can determine x.
YA=17 YH=17*2.375=40.375
The length of side YH=40.375 which is equal to x.
Answer:
A., B.
Step-by-step explanation:
Opposite angles of a quadrilateral inscribed in a circle are supplementary, so their sum must equal 180°.
A. 72° + 108° = 180° Answer: yes
