Answer:
< ABC = 80
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
< ABC = 1/2 ( 160)
< ABC = 80
Answer:
Step-by-step explanation:
When given points, whether that be on a graph or a table, those can be used to find the slope using the equation y2 - y1 / x2 - x1.
y2 - y1 / x2 - x1
(Pick 2 pairs if points. In this case I am using (2, -1) and (-1, 3) from your data table. From here, just plug it in.
-1 - 3 / 2 + 1
-4 / 3
Your slope is -4/3. Hope that helps! Take care.

Answer:
Helen is 24; Robert is 39
Step-by-step explanation:
If Helen's age is x, Robert's age is x + 15. We can write:
x + x + 15 = 63
2x + 15 = 63
2x = 48
x = 24
This means that Helen's age is 24 and Robert's age is 24 + 15 = 39.
The answer is 72 because the vertices are on the lower left corner and the upper right corner. which means that 12 units is the length of the hypotenuse.
