Answer:
you would distribute 3.5 to 2 and 4.5 and get 7h+15.75=57.75 subtract the 15.75 and get 7h= 42 which makes h=6
Answer:
57°
Step-by-step explanation:
The ladder will be the hypotenuse while the 4.2 meters will be a leg.
We want the angle between the ground & the ladder. Therefore, 4.2 is on the opposite side of the angle.
sin(theta) = opposite/hypotenuse
sin(theta) = 4.2/5
theta = arcsin(4.2/5)
theta = 57°
