An observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a 49° angle of elevation from his line of sight. How high is the helicopter flying over the building? You must show all work and calculations to receive full credit. (10 points) A right triangle is shown with one leg measuring 900 and another leg measuring h with an angle across from it measuring 49 degr

1035.33 feet

Step-by-step explanation:

Use the tan function, since we are given an angle and the measures of two legs of the triangle.

tan =

tan 49° =

Multiply each side by 900

900(tan 49°) = h

1035.33 = h

So, the helicopter is flying 1035.33 feet over the building

is means division by fractions

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
