Answer:
21.8°
Step-by-step explanation:
The two sides of the rectangle, 4 inches and 10 inches, make the legs of a right triangle that includes angle A.
The 4 inch side is opposite angle A and the 10 inch side is adjacent to angle A; this gives us the ratio for tangent:
To find the value of angle A, take the inverse tangent of each side:

Step-by-step explanation:
the strut forms a right triangle with the end of the pole.
let the ends of the strut be x from the top of the pole . then
using Pythagoras' identity with 2 legs x and hypotenuse 1.2
x² + x² = 1.2²
2x² = 1.44 ( divide both sides by 2 )
x² = 0.72 ( take square root of both sides )
x = ≈ 0.85 m ( to 2 dec. places )
the ends are 0.85 m = 85 cm from the top of the pole
