y = 3x + 1
Step-by-step explanation:
Answer:
As per the statement:
Shadow of tree = 10 ft
Shadow of boy = 2.5 ft
and
height of the boy = 5 ft
we have to find the height of the tree.
Since, the given triangles are similar their corresponding sides are in proportions
then;
Substitute the given values;
Multiply both sides by 5 we have;
Therefore, the height of the tree is , 20 ft
Remember, sin(|x|)=cos(|90-x|)
so sin(|36|)=cos(|90-36|)=cos(|54|)=cos(54)
answer is C
