Answer:

Step-by-step explanation:
For
, there are two possible cases:

Solving for both cases, we get:

Answer:
X = 10
Step-by-step explanation:
if we say 1/2 base = <em>a</em>
a² = 13² - 12²
a² = 25
a = √25
a = 5
if 1/2 base = 5 then x = a × 2
hence X = 5 × 2 = 10
The ground, the building and the line of sight between the ground camera and the top of the building form right triangle with hypotenuse equal to 45 feet and angle adjacent to this hypotenuse and ground - 50°. The building is an opposite leg to the given angle, then you should write sine function:
.
The answer to the nearest tenth of a foot is 34.5 feet
D is the answer.
Step-by-step explanation:
9 + 6 + 5 = 20
5/20 = 25%
I hope this helps, have a good day!
