Answer:
Step-by-step explanation:
The exterior angle measure is same as he sum of remote interior angles and the adjacent interior angle make straight angle with the exterior angle
<u>So the adjacent angle is:</u>
<u>The other angles are 2x and 3x as per ratio:</u>
- 2x + 3x = 130
- 5x = 130
- x = 130/5
- x = 26
<u>And</u>
- 2x =2*26 = 52°
- 3x = 2*26 = 78°
<u>So the angles are: </u>
The largest angle is 78°
Let x represent the number of boys.
Then 1/2x + 10 represents the number of girls. (there are 10 more than half the number of boys)
We can set up a simple equation for this situation:
# of boys + # of girls = 25 students
so
x + (1/2x + 10) = 25
x + 1/2x + 10 = 25
1/2 = 0.5
x + 0.5x + 10 = 25
1.5x + 10 = 25
1.5x = 25 - 10
1.5x = 15
x = 15/1.5
x = 10
x = # of boys, so there are 10 boys in the class.
Good luck on your math!

Answer: 26.13yards^2
Step-by-step explanation:
To find the area of the bottom part we can use the diameter.
6 yards. Divide it by half to have the Radius.
Now we use the formula to find the area of a circle which is
A = 3.14*R^2 Pie times radius squared.
A = 3.14*3^2
A = 3.14*9
A = 28.26 Now that we have the area of the circle divide it by 2.
14.13
Now to find the area of an isosceles triangle we use the formula
A = Base * Height Divided by 2.
A = 6*4/2
A = 24/2
A = 12
12 + 14.13 = 26.13
