Question

Which equation would you use to find how high the bird is flying?

tan45° = 1100 over x


cos45° = 1100 over x


cos45° = x over 1100


tan45° = x over 1100

Answer 1

tan45 = x over 1100

Explanation:

Because tan = opposite/ adjacent

x is the opposite of the 45 angle in the figure shown

1100 is the adjacent of the 45 degree angle

thus tan45 = x/1100
