Answer:
Step-by-step explanation:
Given
The plane is cruising at an altitude of
The angle of depression is
Suppose the distance of the plane to the runway is x
from figure
(3*3)+(8*2) because triple 3 is 3*3 and double 8 is 8*2
Complementary angles add up to 90 degrees. Therefore, the answer is c. 18 + 72 = 90
Answer:
175 miles
Step-by-step explanation:
Hillary has travelled
320 + 350 = 670 miles
in the first two weeks.
Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.
670 + x = 845
And if we subtract 670 from both sides:
x = 845 - 670 = 175
175 miles
