Answer:
85 cm
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

we have given the complement of an angle as degrees.
we need to find out the measure of angle.
we know that complement of an angle is lesser than or equal to 90 degrees.
so the angle is .option c (53)
where 53 is the measure of angle have 37 degree as complement angle.
