3. Eric is flying an airplane at an altitude of 2200 feet. He sees his house on 1 point the ground at a 45-degree angle of depression. What is Eric's horizontal
distance from his house at this point?
2200 ft
A. 110 feet
B. 220 feet
C. 1100 feet
D. 2200 feet

D    2200 feet

Step-by-step explanation:

Let d = the horizontal distance

tan 45 = 2200/d

dtan 45 = 2200

d = 2200/tan 45

d = 2200 ft.

Another solution is to recognize that the triangle is a 45-45-90 triangle and that the legs are congruent in the triangle.  So, the horizontal leg is the same as the vertical leg = 2200

my answer is$ 12

step-by-step explanation:

because 15 -2=12

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
