Answer:
The angles are 45°, 60° , 75°
Step-by-step explanation:
<h3>
Angle sum property:</h3>
Sum of all the angles of a triangle is 180°.
Equation:
3x + 5x + 4x = 180
Combine like terms,
12x = 180
x = 180/12

3x = 3 *15 = 45°
5x = 5* 15 = 75°
4x = 4 *15 = 60°

LINE THE NUMBERS UP AND IT WILL MAKE SENSE
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.
