2/3 girls that's mean there is 1/3 boys.
If there are 18 girls that mean half this number is the boys which is 9.
Therefore, total number is 27.
In my estimations you have a triangle with 2 angles and an altitude or height. You have to find the base of the triangle in order to find the area. I set up the triangle and sine the 60 degree angle was bisected I know that the vertex angle is 30 in my right triangle. I used the tangent ratio of 30 to find the base of that triangle and then multiplied it by 2 to get that the whole base measure is 27.71281292. Then I multiplied it by the height I was given of 24 and divided the whole mess in half to get the area. 332.553 units squared.
16/80 = 1/5 = 0.2
Therefore, 0.2 x 100% = 20%.
Answer:
<u>x = 65</u>
Step-by-step explanation:
180 - 115 = x
x = 65
Have a nice day!
