Answer:

AB = 4.41

Step-by-step explanation:

cos theta = opposite / hypotenuse

We know theta = 25 and the opposite side =4

cos 25 = 4 / hypotenuse

Multiply each side by hypotenuse

hypotenuse * cos 25 = 4/ hypotenuse * hypotenuse

hypotenuse * cos 25 = 4

Divide each side by cos 25

hypotenuse * cos 25/ cos 25 = 4/cos 25

hypotenuse = 4/cos 25

hypotenuse = 4.413511676

Round to the nearest hundredth

hypotenuse = 4.41

Everything is done right so far.

Now to calculate the height of the tree, 12tan46, put the equation into a calculator.

Either a graphing calculator (make sure it is in degrees, not radians),

or the one on your phone (turn your phone landscape in the calculator app to get the trig functions.))
