Answer:
you would use 85 to find angle 4, because they would add up to 180, so you would subract 85 from 180 to get angle 4
Step-by-step explanation:
Answer:
3 times more.
Step-by-step explanation:
The odds of landing a dart in any of the circles correspond to the surface area of the circle.
Calculate the surface area of both circles:
The formula for the area of a circle is
.
- inner circle:

- for the outer circle, use the formula then subtract the value of the inner circle, to find the remaining area:

Calculating greater chance:
Divide the larger area by the smaller area:

That means that the area of the outer circle is 3 times larger, making it 3 times more likely to hit the outer circle. Therefore the points for hitting the inner circle should be 3 times more.
Answer:
A) By using the Pythagorean Theorem, we will see that
. If we simplify it, we will find that the hypotenuse of Δ
B) approximately 
Step-by-step explanation:
A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!
***Pythagorean Theorem is 
B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be,
.
≈ 
Hope you do well on the rest of your math problems :D
