12sy2 would be the answer
If it is right triangle use pythagorean
Answer:
θ =
Step-by-step explanation:
Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;
Sin θ =
Sin θ =
= 0.5
θ = 0.5
θ =
Thus, the angle of elevation from the base to the top of the mountain is .
Answer:
<1 =73
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
72+ 35 + <1 = 180
Add like terms
107 + <1 = 180
Subtract 107 from each side
<1 = 180-107
<1 =73
