Answer:
I really love and enjoying spending time learning math. My first memories about math lies on a teacher named Humberto. He was very passionate about teaching math to his students and I was one of the best because I always loved math. I remember that I studied a lot because I wanted to get good grades. So the classes of this teacher affected me because I choose electrical engineering as my career. Math in university was very hard, I remember that my first grade in geometry was 03. However, I graduated at last.
Step-by-step explanation:
The rate of eggs per chicken is 120/20=6 eggs per chicken
so.... 30 × 6 = 180eggs
For this, you have to understand the ratios of a 30,60,90 triangle. The ratio(in order) is x, x(sqrt 3), 2x (following the 30,60,90 pattern y'know). Well, we know the length of the hypotenuse, 4.2, so let's use ratios to figure the other sides out. The ratio of AC is x and the ratio of AB is 2x, so 2x/2=x=2.1. One side down. BC has a ratio of x(sqrt 3). We already know x so we can substitute it in. We get 2.1(sqrt 3). To calculate the area, use the formula 1/2(bh). Inputting the values in, we get 1/2(2.1*(2.1(sqrt 3)). This can be calculated to around 3.82. To calculate the perimeter, take the sum of the sides. By adding the sides together, we get about 9.98. Hope you can now understand how to do these kinds of questions.
