Step-by-step explanation:
Los ángulos de elevación hacia un
avión se miden desde la parte superior y la base de
un edificio que tiene 20 m de altura. El ángulo desde
la azotea es de 38°, y desde la base es de 40°.
Calcule la altitud del avión type in English
Answer:
1/3
Step-by-step explanation:
ok so make a common denominator
16/24-12/24=8/24
8/24 reduces to 1/3
How come it’s a right triangle, I think you do a2+b2=C2. Therefore, you do 9.4 times 9.4 and then 15.1 times 15.1. So it will be 9.4 + b2=15.1. 88.36+ b2=228.01. Then you subtract that and it will be 139.65. Then you do square roots because you are trying to get rid of the second power. And the final answer is 11.81736011. How they told you to round it to the nearest tenth, I will be 11.8. I think this is the answer.
Answer:
131.25
Step-by-step explanation:
There are 3 trapezoids that you need to find its area, all the areas are the same.
Area of trapezoid:
A=(a+b)/2*h
a = 20
b = 15
h = (20-15)/2 = 5/2
A = (20+15)/2*5/2
A = 43.75
3A (3 gardens) = 131.25
